I just installed Windows XP on my computer a few days ago. I formatted and then installed XP. I've been trying to play videos on Media Player 8 and I can't play any. I've downloaded the divx codec. When I try to play a video only the audio plays no video comes. I get absolutely no error messages, prompts, dialog boxes nothing. It just plays the audio as if nothing was wrong. I've tried to play .avi, .mpg, .divx etc. All have the same problem - audio works - but no video.

So what is the problem?
