my p.c will no longer play mpeg files properly.this is a disaster as i do a lot of video capturing and editing. neither ulead videostudio, windows media player or realplayer will play the video associated with mpeg files. the file actually opens and runs but only the sound will play. i recently installed directx 9 and the diagnostic tool reports no problems.I also installed nvidia's latest graphics driver but rolled back to the previous one because i thought it was more stable and provided better graphics during gameplay. i can't be specific as to whether my problem started before making these changes but if they are responsible how do i go about getting my mpeg files to run again. my system is a p3 866mhz,256 sdram,two hdd's( 20gb+40gb ) nvidia tnt2 32mb, creative pci 128 sound.

thanks in advance
