Okay I just ripped my copy of Frat Party At The Pancake Festival in .AVI format. It sounds simple enough, but when I open it. Not only do I see my .Avi files, I also get .sub and .idx files. I thought .sub would be it in subtitles. Alright simple enough, but when I try using VLC player, it doesn't play.... Weird. So then I use my Media Player Classic.... Nothing plays. 1 - What are these files 2 - How can I play them, or at least convert them into something where I can play them?
