Unsynchronised playback- small AVI files

Large 700 MB AVI movie files play properly but smaller ones like the 150 MB one-hour AVI file doesn’t play properly. It started when I installed some video players the other day. I uninstalled it later, but the problem’s still there.

What happensis that the audio plays at normal speed but the video moves much faster. You can imagine how bugging it is. And this happens regardless of which player I use, WMP, or mplayer2, or Real Player.

I’ve also installed Windows Media Player 9 and I use Windows XP.

Its very frustrating. Can’t even see FRIENDS episodes on the comp.

Please help.

Thanks,

Kamal
