I've got some .avi videos in my computer. They're generally around 300MB. Downloaded from the Internet actually. I've encountered this problem but I think only with big .avi videos.
When I play them, the sound gradually lose sync with the picture. Sometimes it's pretty up to beat, sometimes it's worse. Usually the sound is faster than the picture, when it gets worse the sound just spoils the story cos you sort of know what's happening before you see it.
Its' really annoying and I know someone else must've encountered this problem before. I know the video itself should be fine cos when I skip/fastforward it, the sound at the next point is actually pretty in sync, then from that point on it gradually loses sync again.
Oh btw, I've tried to play the video with Windows Media Player 10 and Media Player Classic 184.108.40.206. Both got the same result.
Please someone help.
