I have Windows XP running Windows Media Player 8, trying to play some mpgs which apparently are in mpeg1 format. The problem is... it will freeze, skip or stop playing part of the way through on almost all of them (about 25 or so). In addition to the playback, occassionally the status bar (which shows how far into the movie you are) isn't correct. It will get to the end on the status bar but continue playing. I have uManic's XVid build and NIMOs codecs loaded. I'm guessing I overwrote something and that's causing bad playback. Anyone have any idea of how to fix this? I'm assuming I'll have to re-install a codec... but I'm not sure which one. Thanks for any help!
