I am trying to play divx movies and it says I do not have the proper video codec fourccc 0, how do i get these to play... IF i go to properties it says the codec name is compressed? 
I also have the same problem. Prob, just corrupt files.

“Please note that there doesn’t exist any video codec that uses the FOURCC code 0. If you’ve downloaded a movie with the FOURCC code 0 it’s a fake movie file and you won’t be able to watch it. To avoid fake movies using KaZaA you can use a program called sig2dat. Then you simply goto a site such as FastTrackMovies.com and lookup the movie you want to download. All the files have been verified and should work, so when you follow the sig2dat link your KaZaA will automatically try to find and download the movie."
