I need help with torrents, can you help me?

Yes, I know it is illegal, but this is the last option I have. I was trying to find a DVD of CMT Crossroads with Martina McBride and Pat Benatar, and was unable to find ANYTHING. I finally did find a torrent, and I downloaded it along with uTorrent. Once I finished downloading it, I went to play it and it only has the audio. Did I download it wrong? can someone help me? I am fairly computer literate, however, I know nothing about downloading Torrents, I know none of the language or anything, so please walk me through step-by-step. Thanks.
