I'm trying to watch a movie online (Hot Rod) on a site with the DivX version because that's the best quality, anyways, I have the DivX player so the video works but every time I try using it it comes up with a message that says: "This file contains a track in an unknown format. You may need to install a DirectShow decoder for this audio format in order to hear the soundtrack of this file." I don't really understand what that means....so can someone help me? Where would I download it???? Links would be great!
