Anyway, since that, a lot of mpg files that I'll try to play won't run properly. What happens is that an mpg file that's about, say, 30 mins will be only around a minute according to the player (the exact time varies from file to file but remains consistent with individual files). If I skip around the video file I can get to different parts of the video, but the player (whatever player I choose to use, be it WMP, Winamp, DivX player, or whatever) still thinks the file is around a minute in total, so say I skip to halfway through the time bar, I might get to a point in the movie that's around halfway through, but the player will think there's only about 30 seconds left. Sometimes if I leave it playing, when it gets to the end the sound keeps going, then it'll skip back to where the time bar started and keep playing for another few seconds, and so on.
The problem isn't the files themselves, I've tried copying them onto other computers and they worked fine on there. I've tried downloading codecs to no avail. I've tried converting but on this computer of course even the video editing programs think the file is around a minute long and so they only convert the first minute or so. I could convert the files on a different computer but that doesn't get to the root of the problem.
Does anyone have any ideas?
