    I've downloaded several .mpg's and many of them say they are x length but are in fact a lot longer. Say it reports it to be 5 minutes well the bar reaches 5 minutes then the audio continues as normal but the video stops completely. However if I was to go to a third of the way through by clicking on the timeline you would get to see new playback following on (well missing some frames) from the end of those 5 minutes you just watched. This would then play back to the end of those 5 minutes (of course you wouldnt get 5 minutes as you're already a third into it). Again this wouldnt finish properly so I tried selecting half-way through and the playback continued as before. And so on ...
    Is there any way this can be resolved or is this just a corrupt video file? If so though how is it able to play a 20 minute movie split up so it looks like its only 5 minutes.
    I've used many different video playback software but they all play the same thing.
    Sounds bit confusing but is rather hard to explain!

    Maybe the file is corrupted. Like maybe some bad frames in the video. If this were an avi id recommed using something like divfix or avifix to try and rememdy the problem but since youve got mpegs the only way to do this is to convert to .avi by opening it in virtualdubmod or use TMPGenc to output the file as an avi. Both methods degrade quality though...Maybe you can try resaving the mpeg with TMPGenc. This seems to work with some avis when you need to rebuild the film's index.

    Also this might be a video codec problem, so download GSPOT and load the movies in the program to see which codecs you need.

    I have the exact same problem. its doesnt have anything to do with the player, every player will play it with a wrong length. This is really p*ssen me off, ive got a lot of mpeg files and i want to veiw them at full length.

    Re-compressing it wont help either, it just compresses the part that windows media player or any other player would play.

    ANYONE know how to get them to play properly??
    The files arnt corrupt.

    Are you able to watch the rest of the clip by moving the seek bar past where it always stops?

    I'm not sure who you were addressing but how can you go to a later part of the movie when it has already reached the end of the seek bar? Surely there should be no new playback after (although the audio continues which is puzzling).
    I dont get how if you play it from start to finish it will only play for 5 minutes (for eg) yet if you select say half-way through you see something that wasnt in the original first 5 minutes. Does anyone know how this is possible and if so if its correctable?
    I've used G-Spot on them all and no errors found.

    That post was meant for The_Dunc.

    So you mean in your movies you reach the end of the seek bar but the audio keeps playing? That seems odd.

    What I meant is if the video was say 90 minutes and it stops exactly at 30 minutes everytime, would you be able to watch past the 30 minute mark by moving past it on the seek bar.

    Hello, I found this thread while trying to find a solution to a problem almost the same as you're having scomfort.

    Several of my video files have recently started reporting the wrong time too, however my video keeps playing in addition to the audio. For instance, I can try to play a 40 minute video and the timer bar reaches the end at 3 1/2 minutes. The video and audio continue to keep going although the bar and timer stay at 3 1/2 min. I too can skip well past the 3 1/2 minute part in the video if I slide the bar over before it reaches the end. G-spot doesn't report any problems or strange codecs used and I know the files are not currupt because files that I used to watch perfectly are now malfuntioning.

    I'd be really grateful to anyone who can help with this! I've been fighting with this problem for almost 2 weeks now and it's extremely frustrating. :(

    That is a strange problem...
    Have you downloaded any recent codec packs by chance?

    I likely have recently installed some codec packs. I'm always downloading crap. :) After I realized that it wasn't the files that were corrupt and that it was something else, I uninstalled just about everything that I could find and reinstalled only what I absolutely needed, but it didn't do any good. I will admit that audio and video codecs are not my area of expertise at all, so I may have missed something crucial while reinstalling codecs...

    I've used system restore to back my comp up as far as I could and even tried reinstalling windows, but that didn't help eihter. I dunno, this one's got me stumped, and I can't think of anything else to try...

    Hey, sorry i havnt bin online for a while.

    It seems to me the problem startet when i installed kazaa lite codec pack. Iv tried uninstalling it but no luck. I found a very interesting theory online, it explains that its all got to do with the sound card.

    http://www.scala.com/discussions/mpeg-files-playback-with-wrong-time-please-help-1646.html

    Ive reinstalled my audio driver but nothing changed. THE ONLY WAY TO WATCH THESE FILES IS WITH REAL PLAYER.

    If anyone has the cure please post it.

    Just tried using Real Player to play these troublesome movies and they all play fine so thanks for that! (i.e. report the correct time - video plays for correct time so can just hit play and wont have to mess around with the seek bar). Although anyone know why Real Player plays it fine but others such as WMP, Adobe Premiere and others dont?

    Really by using RealPlayer, it fixed up the movies?

    Thats interesting, maybe the problem lies withing WMP. Have you tried upgrading WMP?

    Yeh I have the latest version of WMP although no help. You would also think a professional video editing package such as Adobe Premiere would play it properly but no!
    Did everyone else who had these problems find Real Player played the mpg fine?
    Any ideas why? Everything plays fine now; I'm just wondering why Real Player play certain mpg's fine and the others dont!

    Been away from my comp for a few days, but after reading this, I re-installed RealOne Player and the files play perfectly. Well, almost perfectly. The timer and bar work fine, but the video and audio stops between 3 to 8 seconds before the end of the file and the timer finishes the countdown the last few seconds with a frozen video and no audio. I tried several of these files and it did it on all of them. That suggests to me that there is a problem with the way the end of these files are encoded, but it could just be the players. Still, losing a few seconds is a hell of alot better than having problems with the majority of the file. NO Other Player will play them that well.


    Oh, interestingly the problem with the videos(for me) originally arised approximately the exact same time as when I uninstalled Real Player a month ago or so. Probably just a coincidence....

    If you have avis, maybe you can fix the problem by resaving the movie in virtualdubmod.

    Hey, I recently got this problem where my MPEG files would either display incorrect time, or reach the end - keep playing the sound... or just skip through the whole file.

    Well, ok actually this happened on my favourite porn MPEG and the movie was finishing up before I was. Anyway, I was looking for a solution and I found this forum. And none of you guys can figure it out... anyhow after 5 minutes of tinkering... I might have a solution for SOME of you.

    On all the MPEGs using MainConcept mpeg splitter there is a problem. all other MPEGS are fine. So, if any of you have movie authoring software such as premier etc... you need to remove the splitter filter

    Find this file "mcspmpeg.ax" in your windows\system32 or windows\system directory. Rename it to "mcspmpeg.ax.bak" and try your MPEGs. It should fix the problem. If you need to ressurect this file, just change it back.

    Hope this helps. And happy porn watching! Yahooooooo :D

    You, kip0r, are currently like my favorite person in the whole world right now :). I didn't have the file you mentioned on my computer, but GSpot helped me locate the splitter that was giving me problems with some files (mpeg2dmx.ax) and after changing it the problem seems to be completely fixed. ^_^ Thank you for the idea kip0r!!

    For anyone else suddenly having similar troubles with your mpg's, try renaming the [bold]Splitter[/bold] to force your computer to use a different one.
