mpeg problem

[livininthematrix]

Ok heres my problem. For a long time i played mpeg files with no problem at all. All of a sudden a couple weeks ago, every mpeg file i play with windows media player, i have a problem with. The most common problem i have is that when i play the mpeg file, say the file is a 20 minute video, it will play 1 minute or so of the video, then the slider reaches the end, and the video cuts off, but the sound continues to play. Trust me, ive already uninstalled and reinstalled my codecs, even did a uninstall with windows media player. And another weird thing that happens is sometimes when i restart my comp and immediatly play the mpeg file, it will run perfectly, but then if i try to play it a second time, it will mess up all over again. WEIRD STUFF. Pleassssse someone help me out, all comments are appreciated. Thank you in advance, Scott.

Something changed a "couple of weeks ago"
What OS ?, SYs config? , ETC.
Did you recently 'upgrade' Mplayer??
What version Mplayer are you using?
Before you can get help , you need to ask for it , in a more specific way
