Sopranos Season 5 Episode 13?

I have downloaded a lot of different Sopranos season 5 episode 13 files only to find they appear to be audio files when I check them with AVI Codec?

I have downloaded all the latest codecs and I can't see the episode, Am I missing something here?

thank you,

Does anyone have a real copy of Sopranos season 5 episode 13? Is this the season finale?

Its on SuprNova.org. Download GoSupernova to search for it.
