I need some help with torrents again. I've downloaded 3 or 4 avi video files from torrent sites that have been in really good quality but they've got no sound. Am I doing something wrong that is making them like this or is it just the file? I don't think it is just the file because the video is really popular with hundreds of seeds and whatever, and I don't think all these people would keep the video if it had no sound lol.

The video I just downloaded with no sound was Blades of Glory from IsoHunt if that helps...
