.avi file with no video

I’m new to BitTorrent. I recently downloaded a video. Upon playback, the sound works fine but the video just doesn’t show up at all. I’ve tried it in winamp, quicktime and windows media player, all to no avail.

This is the file name:

the.o.c.202.hdtv-lol.avi

Any suggestions?
