1718: Thanks very much for your company today. Hope you enjoy what's left of Saturday. We're back tomorrow with all the goals in our video highlights on the website, plus live text and audio coverage of Arbroath v Rangers and Peterhead v Celtic. All the best.
1711: If you are allowed to stay up late, don't miss Sportscene on BBC One Scotland at 2220 GMT for a round-up of the day's action.
1711: AlisonRobbie on Twitter: "Billy Reid says #hamilton tactics paid off this afternoon."
1709: FULL-TIME: Livingston 1-2 Ayr United
1708: "Great credit to the players for getting the result. However, we realise there is a lot to be done." Aberdeen manager Craig Brown is satisfied with the 4-0 win at Forfar, though he is worried at the addition of Isaac Osbourne and Peter Pawlett to the Dons' injury list.
1704: I just have to share with you this text from Mark in Saltcoats which he sent when the score at Tynecastle was tied at 0-0. "Amazing to think that a team who don't get paid and are painters through the week are drawing...with Auchinleck!"
1701: Oh, dear. You feel for Chris Smith - four minutes into injury time, he and his Dunfermline team-mates were on the cusp of a win at the Caledonian Stadium but the Pars keeper completely missed the ball, allowing Inverness winger Jonny Hayes in to score the equaliser and force a replay on 17 January.
1700: Cracking text from Chris in Fife, making reference to Dundee United's convincing win at Airdrie: "Jim Traynor will be six-two his stomach!"
1658: The only fourth round tie still being played this afternoon is Livi v Ayr, where Brian Reid's side are leading the hosts 2-1.
1657: FULL-TIME: Inverness CT 1-1 Dunfermline
1656: GOAL! Inverness CT 1-1 Dunfermline (Hayes)

1650: FULL-TIME: Raith Rovers 1-2 Morton Cowdenbeath 2-3 Hibernian Motherwell 4-0 Queen's Park Falkirk 2-0 East Fife St Johnstone 2-1 Brechin Partick Thistle 0-1 Queen of the South

1641: Gordon Smith fires home for Hearts after Auchinleck goalkeeper Andy Leishman drops the ball in a collision with his own captain, Bryan Slaven.
1640: GOAL! Hearts 1-0 Auchinleck Talbot (Smith)
1637: I'm sitting beside a Hibs fan today. He can't enjoy Hearts' predicament against Auchinleck because Cowdenbeath are running rings round his own team at Central Park in the second half.
1636: Moments after Cowdenbeath keeper Thomas Flynn made a good save to keep out a stinging Callum Booth shot, John Robertson squanders a great chance to level - slicing wide when he could see the whites of Mark Brown's eyes.
1635:MLeRoy on Twitter makes an interesting point about the dates of replays at Rugby Park, if Auchinleck draw with Hearts: "RE 1616: The day after Killie Dundee? The pitch isn't exactly at its best at the moment. 2 games in 2 days won't help. #bbcsportsound."
1632: Auchinleck goalkeeper Andy Leishman blocks at point-blank range to deny Rudi Skacel after the Hearts winger was found by David Templeton's through ball.
1631: GOAL! Motherwell 3-0 Queen's Park (Murphy)
1631: GOAL! Forfar 0-3 Aberdeen (Fallon)
1630: GOAL! Ross County 5-0 Stenhousemuir (Vigurs)
1629: Poor Darren Barr - he goes off with an eye injury to be replaced by Gary Glen. Hearts have now made all three substitutions.
1628: You'll have been wondering about that goal for the Blue Brazil at Central Park... It has a familiar ring to it: John Robertson scores against Hibs. Cowdenbeath are right back in it as the flame-haired midfielder flicks a high ball over an opponent and finishes in style with a lovely volley.
1627: GOAL! Airdrie United 0-5 Dundee United (Mackay-Steven)
1626: I'm turning in to a human vidiprinter...!

1623: GOAL! Airdrie United 0-4 Dundee United (Russell)
1623: GOAL! Raith Rovers 1-1 Morton (Campbell)
1620: These Talbot players could become superstars after their appearance on Sportscene at 2220 GMT on BBC One Scotland this evening. If you are in the UK but not in Scotland, make good use of your digital TV coverage by finding Sportscene on the BBC One regional/national variations - you know it's worth it.
1619: With most matches going as expected, all eyes and ears will begin to focus on events at Tynecastle where Hearts and junior side Auchinleck Talbot are locked at 0-0.
1618: GOAL! Airdrie United 0-3 Dundee United (Russell)
1617: GOAL! Ross County 3-0 Stenhousemuir (Gardyne)
1616: I've just checked the SFA website - the replay between Auchinleck and Hearts would be at Rugby Park on Wednesday 18 January.
1613: An anonymous text sets us a question: "If Talbot manage a draw would the replay be allowed to be played at Beechwood [Auchinleck's home ground]?"
1612: scotbot on Twitter: #Hibs now on easystreet. Perhaps this will mark a change in league form. Here's hoping anyway. #bbcsportsound #scottishcup"
1610: About 1,700 Auchinleck Talbot fans are watching their team hold Hearts at 0-0 at Tynecastle. That's about half the town's population.
1610: Hibs move further ahead at Central Park as David Wotherspoon dives to meet a Danny Galbraith delivery and flicks a neat header in at the near post.
1607: Graeme in Banchory by text: "At Station Park and the stand opposite us is practically empty. I mean, if u can't half fill a wee stand against an SPL side then there isn't much hope."
1606: GOAL! Ross County 2-0 Stenhousemuir (Brittain pen)
1605: SENT OFF: Ross McMillan (Stenhousemuir)
1604: I'll have to take Kris from Rosyth's word for it in his text: "His goal today means Farid El Alagui has scored against 14 of the 16 teams he has faced this season. Scottish Football can't handle him. COYB." Thanks, Kris.
1603: GOAL! St Johnstone 2-1 Brechin (Sandaza)
1602: HALF-TIME Livingston 1-1 Ayr
1601: Second halves commencing roonabootnoo.
1559: aihenderson on Twitter asks of Fraser Mullen being given the responsibility to take Hearts' penalty, "Why is a boy on his debut taking a pen?" Hmmm, quite.
1559: GOAL! Livingston 1-1 Ayr United (McNulty)
1557: This text from Andrew in Dundee made me laugh: "Can Sandy Clark sound any more depressed when describing Dundee United goals? Not for the first time at a United match he is unable to hide his dislike for the club!" Well, he loves the Diamonds, does Sandy.
1553: Don't miss the highlights of all today's fourth round games on Sportscene tonight at 2220 GMT on BBC One Scotland.
1551: yogs1967 on Twitter: "#bbcsportsound Watching another dreary English FA Cup game here in Perth Australia - would rather be watching the Scottish Cup games!"
1548: HALF-TIME St Mirren 0-0 Hamilton Accies Ross County 1-0 Stenhousemuir Partick Thistle 0-0 Queen of the South Inverness CT 0-1 Dunfermline Motherwell 2-0 Queen's Park Airdrie United 0-2 Dundee United
1545: Added that Pars goal lower in the text... This is (enjoyable) madness!
1543: St Mirren's Gary Teale is denied when one on one with Hamilton keeper David Hutton, in for Tomas Cerny today.
1542: GOAL! Airdrie United 0-2 Dundee United (Scott Robertson)
1541: GOAL! Raith Rovers 1-0 Morton (Clarke)
1538: Good to hear that David Goodwillie has scored for Blackburn. Nothing against Newcastle, mind you.
1538: Kilburn Dave on Twitter: "Open all Mics on Sportsound was made for Scottish cup 4th round weekend... Love it! #bbcsportsound #aberdeenfc"
1536: A few minutes back, Leigh Griffths rattled the crossbar with a dipping free kick from 30 yards. Hibs are well on top.
1535: Auchinleck goalkeeper Andy Leishman is the junior side's hero again as he produces a terrific save from a deflected Rudi Skacel shot.
1534: "It's more chiller than thriller," bemoans Chick Young at St Mirren's match against Hamilton.
1533: Bunion-No9: "Can't believe that with the preached philosophy of Kenny Shiels that he deems Sissoko to be a football player, the guy has been a gift-horse to the opposition too many times this season!"
1528: Michael Hart is given far too much time on the ball by a retreating Cowdenbeath defence and his pass finds Eoin Doyle, who tucks in the rebound from a tight angle after his first effort was blocked by the foot of Thomas Flynn.
1528: GOAL! Cowdenbeath 1-2 Hibernian (Doyle)
1526: What is it with Hearts and missing penalties? Their four missed penalties have been missed by four different players.
1524: So far, so good in terms of goals around the country. Six of the 13 games have produced goals by the midway point in the first half.
1523: GOAL! Falkirk 2-0 East Fife (El Alagui)
1522: GOAL! Motherwell 2-0 Queen's Park (Murphy)
1521: Back to that Hibs goal... The Edinburgh side are level thanks to a stunning strike from Leigh Griffiths. Cowdenbeath manager Colin Cameron will be kicking himself for giving the ball away in the move that led to the goal.
1520: Fraser Mullen, making his debut for Hearts, makes it four penalties that his team have missed in a row in a month. Andrew Leishman is Talbot's hero between the sticks. Hearts won the penalty when Gordon Pope tugged Arvydas Novikovas' jersey.
1519: Hearts have a penalty! A stonewall penalty, according to impartial Allan Preston.
1519: GOAL! Cowdenbeath 1-1 Hibernian (Griffiths)
1518: An anonymous text to 80295: "What planet is Kenny Shiels on? 'Douse tribal enthusiasm and introduce more quality' - really? Is that what he wants for football, no passion just the rustle of sweetie papers, why does manage a football team, he should manage a museum."
1517: Aberdeen have a goal disallowed at Forfar. Relief for the goalie, who had made a hash of things.
1516: GOAL! Airdrie United 0-1 Dundee United (Rankin)
1515: KillieMad on Twitter: "#bbcsportsound With Talbot's support today and Ayr's semi ticket sales, are Auchinleck now Ayrshire's 2nd biggest team?"
1513: FORFAR TEAM TO PLAY ABERDEEN: Paterson, Ross, Iain Campbell, McCulloch, Tulloch, Mowat, Fotheringham, Wilson, Hilson, Templeman, Ross Campbell. Subs: Mordente, Byers, Motion, Gibson, Ried.
1511: We learn that BBC commentator Liam McLeod is sitting beside Open winner Paul Lawrie at Aberdeen's match at Forfar. We'll never hear the end of this, I fear.
1511: A terrible clearance from Hibs left-back Callum Booth lands at the feet of Scott Linton but the Cowdenbeath man's shot from the edge of the penalty box flies high over the crossbar.
1510: "Auchinleck are not being overawed by their task so far and there has been some good pressure from the junior side." BBC Scotland commentator Alasdair Lamont at Tynecastle
1508: GOAL! St Johnstone 1-0 Brechin City (Murray Davidson)
1507: GOAL! Falkirk 1-0 East Fife (Dods)
1506: GOAL! Ross County 1-0 Stenhousemuir (Vigurs)
1506: GOAL! Motherwell 1-0 Queen's Park (Daly)
1505: A lovely dummy from Eoin Doyle presents Leigh Griffiths with a perfect chance to level for Hibs but the striker duffs his shot horribly wide in complete contrast to the composure shown by Greg Stewart.
1504: That Cowdenbeath goal is the only one in our games so far...not surprisingly.
1503: What a start for the Blue Brazil against Hibs! You couldn't make it up!
1502: Cowdenbeath are ahead inside 60 seconds at Central Park as Greg Stewart dumps Sean O'Hanlon on his backside with a neat turn and lifts a cool finish beyond Mark Brown.
1458: LIVINGSTON TEAM TO PLAY AYR: McNeil, Kyle Jacobs, Craig Barr, Watson, Fordyce, Keaghan Jacobs, Fotheringham, Scougall, Robert Barr, McNulty, Russell. Subs: Jamieson, Fox, Sinclair, Boulding, MacDonald.
1457: I'm seeing perhaps the most bizarre image of this season so far on my monitor. The grim-faced Hibs players are in the tunnel at Cowdenbeath's Central Park and beside them is Bluebell, the hosts' big coo of a mascot. I swear Bluebell was preparing for the match by tucking his jersey into his shorts. Those udders keep getting in the way.
1455: EAST FIFE TEAM: Michael Brown, Scott Durie, Cook, McCormack, White, Muir, Linn, Darren Smith, Wallace, Janczyk, McQuade. Subs: Collier, Campbell, Robert Sloan, Johnstone, Hislop.
1455: FALKIRK TEAM TO PLAY EAST FIFE: McGovern, Duffie, Scobbie, Dods, Wallace, Murdoch, Weatherston, Mark Millar, El Alagui, Higginbotham, Sibbald. Subs: Bowman, Rhys Bennett, Dick, Dale Fulton, Alston.
1436: ROSS COUNTY TEAM TO PLAY STENHOUSEMUIR: Fraser, Miller, Boyd, Munro, Morrison, Brittain, Kettlewell, Lawson, Vigurs, Gardyne, Craig. Subs: Malin, Byrne, Quinn, Morrow, Cooper.
1436: And for the home team ST MIRREN: Samson, van Zanten, McAusland, Mair, Tesselaar, Barron, McLean, McGowan, Carey, Mooy, Hasselbaink.
1435: HAMILTON TEAM NEWS TO PLAY ST MIRREN: Hutton, Kilday, McLaughlin, Canning, Hendrie, Crawford, McAlister, Mensing, Gillespie, Imrie, Spence.
1433: And Barry Smith adds: "The players should be upbeat that they have competed against a good Premier League team."
1431: "It's all to play for in the replay," says Dundee manager Barry Smith. And he has no complaints about Steven Milne's first-half goal being disallowed for offside.
1425: Manager Tommy Sloan reckons they might have around 2,500 supporters at Tynecastle. Over at Livingston, their match against Ayr has been delayed until a 1515 GMT kick-off.
1423: Now, there could be an interesting little stat at Tynecastle this afternoon. If Auchinleck Talbot take more than 3,500 fans to Gorgie they will have more supporters than residents of their Ayrshire town.
1422: stvcbl on Twitter: "#bbcsportsound anyone care to guess how many games Queens Park played in the cup in the 2 seasons they were runners up?"
1420: FULL-TIME: Dundee 1-1 Kilmarnock
1417: It's a midfield tussle. Will there be a last-minute moment of genius or a howler of an error to break the deadlock?
1415: Unless there is a goal at Dens, we are heading for a replay on Tuesday 17 January.
1413: Good effort by Killie's Liam Kelly, who takes advantage of the space afforded to him by the retreating Dundee players, and skelps a shot over the bar from 25 yards.
1410:"BBCAlLamont on Twitter wishes he were a football anorak: "Hearts make 8 changes from team that beat Hibs but still strong looking team. Auchinleck along familiar lines (he bluffs)."
1409: Back to the opposite end now and Killie striker Paul Heffernan's shot from close range is blocked by Craig McKeown.
1407: At the other end Cammy Bell makes two fabulous saves, first from the feet of Steven Milne then from a downward header that was going in to the corner of the net before Bell's athletic dive to prevent it.
1405: Liam Kelly should have headed Killie ahead but, at best, he got his shoulder to the looping cross from the right.
1403: Fourteen minutes to play. There is no extra time; we could be heading for a replay.
1402: Jamie McCluskey makes way for Dundee's Jake Hyde.
1400: And the Spiders were FA Cup runners-up in 1884 and 1885.
1359: Queen's Park, by the way, have won the Cup 10 times...all in the 19th century.
1357: JaneLewisSport on Twitter with some early Motherwell team news: "4 changes 4 #motherwell v #queenspark. OUT Hutchison Hughes Lasley Higdon. IN page Forbes Daly McHugh. 1 change 4 visitors Megatt 4 Burns."
1355: Killie captain Manuel Pascali almost scores his second header of the match, as he meets Dean Shiels' corner and nods a fraction wide of the right-hand post from six yards.
1352: Good grief. Let's go back a moment. Mo Sissoko barged into the back of Ryan Conroy in the penalty box and was booked for his clumsy challenge. But Lockwood's left-footed penalty was weak and too direct. Dens boss Barry Smith looks like he could start bubbling after that chance to go 2-1 up was wasted.
1351: Cammy Bell makes a comfortable save from Dundee's Matt Lockwood!
1350: Dundee win a penalty!
1348: Gavin Rae's lay-off for Gary Irvine is cleared in the nick of time by Garry Hay.
1346: BBC Radio Scotland commentator John Barnes informs listeners that Kilmarnock have won only three away games in 12 months. And he is A Man Who Knows. I've seen the research the man does before a game.
1345: Which team is the hungrier? This could get nervy at Dens Park.
1343: Killie's James Dayton who, when on his game looks like he is a wonderful player, is substituted by Kenny Shiels, with William Gros coming on.
1341: And, after a mini fumble (sounds like an Easter bun), the Dundee keeper collects an in-swinging free-kick into "the mixer" by Kilmarnock's Dean Shiels.
1339: Dundee goalie Rab Douglas rolls back the years to tip Garry Hay's pile-driver over the bar.
1334: Gavin Rae makes a punishing run into the Killie half, passes to Ryan Conroy on the left and his low cross into the middle is poked home by Steven Milne after only 22 seconds of the second half.
1334: GOAL! Dundee 1-1 Kilmarnock (Milne)
1333: Kilmarnock get the second half under way. No changes to either side.
1330: Ross Ewen on Twitter: "Not sure on many Scottish Cup upsets but a sneaky feeling Cowdenbeath will cause one against the Hibees!"
1327: A bit like Blackadder's Baldrick etching his name on a bullet in the First World War trenches, I am going to intentionally type Auchinleck Tablet now before their game starts to avoid making the typo later in the day.
1325: Auchinleck Talbot manager Tommy Sloan tells BBC Scotland viewers that his team's match against Hearts at Tynecastle isn't as big as when Talbot play Cumnock!
1323: Did you know, the last time Hibs won the Scottish Cup, wa-a-a-ay back in 1902, they had an Irish manager - Dan McMichael? Is current boss Pat Fenlon aware of this?
1316: Killie's Rory McKeown dispossesses Jamie McCluskey down Dundee's right wing after the Dark Blues player gets caught in a fankle with an attempted step-over.
1314: Three minutes left of the first half. Dundee would love to get level before the interval.
1311: KillieMad on Twitter applauds ref Stevie O'Reilly for correctly disallowing the Dundee goal: "Referee should be credited for checking that the linesman had seen the crucial flick."
1309: I'm scratching my head at that tweet by Ali Robbie at 1253. Hope that wasn't a retweet I've credited as being from her - she is Forfar's number one fan! "Forfar now my 2nd team"? Think I've got it wrong...
1307: And Killie are a whisker away from going two goals up! Paul Heffernan scampers down the right and eventually gets the ball under control to Dean Shiels who spins and sclaffs a shot an inch or so wide of Rab Douglas's right-hand post.
1306: Well, that goal comes against the run of play to some extent. Murdo's warning was justified, but not heeded.
1304: Manuel Pascali heads the visitors in front, rushing on to meet Dean Shiels' corner from the left. All too easy for the Ayrshire side; rubbish marking by the hosts. They'll be livid.
1303: GOAL! Dundee 0-1 Kilmarnock (Pascali)
1303: "Dundee have got to get themselves in front while they are on top. The longer the game goes on, you imagine Kilmarnock will get one or two chances." BBC Scotland football pundit Murdo MacLeod
1300: Bleugh. Jamie McCluskey balloons the set-piece high over Cammy Bell's bar. The Dundee man hangs his head in shame.
1259: Dundee have a free-kick 20 yards out...
1257: I'd like to see a replay of the "goal" that wasn't, just to clarify who over-ruled whom. The ref might have awarded the goal and then changed his mind.
1256: James Dayton passes to Killie's Irish striker Paul Heffernan but he drags his shot wide from the edge of the box.
1253: Alison Robbie on Twitter: "C'mon the Loons! Aberdeen always dodgy in first games in Cup....send them packing! Forfar now my 2nd team!"
1251: "I have absolutely no idea why they have changed their decision. But, having seen it again, the bottom line is that they got it right." BBC One Scotland pundit Craig Paterson
1249: That, in fact, was an excellent decision that could very easily have been missed. Milne was onside when the ball was played from midfield, but the flick-on by Chisholm occurred after Milne had made his dash for goal. The linesman didn't spot it but ref Stevie O'Reilly was sufficiently eagle-eyed.
1246: Well, what drama! Steven Milne pokes the ball past Cammy Bell to give Dundee the lead. But the "goal" is not given because a flick-on by Ross Chisholm meant Milne was offside.
1244: Paul Heffernan does well down the left and crosses for Kilmarnock's Dean Shiels who cannot quite get space to make a powerful effort at goal and the ball trundles wide.
1242: Mohammed Sissoko mis-times his clearance of a ball across the box but when it to Gavin Rae his rushed effort is partially blocked and Cammy Bell has an easy save to make. It's a good spell for the hosts.
1241: Dundee have two chances in quick succession. First, Gary Irvine gets on the end of Gavin Rae's flick but cannot get enough purchase on his stabbed shot, then Ross Chisholm's lob is saved comfortably by Killie keeper Cammy Bell.
1238: "I know longevity works for goalkeepers but not for players, but to still be playing at nearly 40 speaks volumes for his professionalism." Dundee's Rab Douglas will be pleased to know that BBC One Scotland pundit Craig Paterson doesn't consider goalkeepers to be players. We must assume Craig meant "footballers", rather than "players".
1237: Gavin Rae helps to launch a counter-attack for Dundee as the home side break from a Kilmarnock corner.
1236: Two-thirds of the pitch is in shade - after the past few weeks of filthy weather that we've endured in Scotland, the players could be forgiven for playing the match in the sunny third.
1234: Dundee are in their customary dark blue jerseys, Killie are in their blue and white stripes. Good to see big Rab Douglas in action. He hoofs the ball clear with Killie striker Paul Heffernan closing him down.
1232: The game has begun. Let's hope it's a cracker.
1231: Well, almost. The flimsy advertising hoarding behind the teams topples over and hits the officials while the players exchanging handshakes.
1229: OK, to Dens then, and the teams are making their way out on to the park, with some weak sunshine giving us all a welcome reminder that the darkest days of winter are behind us.
1227: The Old Firm get involved in the fourth round action tomorrow. Arbroath take on Rangers at Gayfield, while Celtic are also in the north-east of Scotland, playing Peterhead.
1225: Five minutes until kick-off. The live video feed is now at the top of this page. I hope you can see it - if you are in the UK - but if not, please reload the page. If you are watching Sportscene online or on a mobile, studio guests Billy Dodds and Pat Nevin will look really tiny but don't be put off.
1224: "Kilmarnock are a good passing team, but we will play to our strengths, which is passing as well. We need to be cautious as Kilmarnock have done well in the SPL, but the boys are looking forward to testing themselves against an SPL side." Dundee manager Barry Smith
1223: "There is not much difference between the bottom of the SPL and the top of Division One, so we are treating this as an away SPL fixture." Kilmarnock manager Kenny Shiels
1221: Not wishing to worry the Hibs fans but Cowdenbeath, their opponents at Central Park, are unbeaten at home in the Second Division this season, winning seven and drawing two.
1219: Killie have been blowing hot and cold but I still fancy them to win at Dens, even though the Dark Blues are going well - they're third - in the First Division.
1217: There are 13 other Cup matches at 1500 GMT, including Cowdenbeath v Hibernian and Airdrie United v Dundee United. You can follow all the action here and on BBC Radio Scotland's Open all Mics coverage.
1214: My Sportscene colleagues will have live coverage of the Dundee v Killie match. The programme starts at 1215 GMT on BBC One Scotland, and here on the BBC Sport website.
1213: As always, we'd be delighted to hear from you. Get in touch using your mobile - send us a text to 80295, or use Twitter with the hashtag #bbcsportsound.
1209: DUNDEE TEAM TO PLAY KILMARNOCK: Douglas, Irvine, McGregor, McKeown, Lockwood, McCluskey, Rae, O'Donnell, Chisholm, Conroy, Milne. Subs: Gibson, Bayne, Hyde, Benedictis, Mcintosh.
1207: We've got the team news from Dens Park...
1205: Our first game today is Dundee v Kilmarnock, kick-off 1230 GMT. Anyone fancy that as a potential shock? Indeed, would it be a surprise if the Scottish Premier League side lost at Dens Park?
1200: Good afternoon and congratulations for choosing BBC Scotland as your guide to the fourth round of the Scottish Cup. I hope when you click off this page or switch off your phone, you do so, um, entertained. If you're a football purist it might be best to hit the back button or lose your phone: this is football, but it may not be as you know it.
