I have this weird problem where when I try to watch some AVI files, it says "Windows Media Player cannot play this file. The file is either corrupt or the player does not support the type of format you are trying to play." I know this is wrong because some of the AVI's used to work and I could view them. Even weirder is that I used Gspot to see what codec is used, and it says, "Not a valid AVI file." Does anyone have a solution for this? I think it might have to do with the codec I'm using. I have both DivX 5.1.1 Pro and XivD installed. HELP!
