Ok I downloaded mac the ripper and ripped Jackass 2 which I just bought. The folder that I ripped it to is full of these files which are .VOB, .BUP, and .IFO. I have no idea what any of those are. What program should I used to watch them? (I only did the main feature extraction). Second of all, how (what program is free?) do I convert them to mpeg-4? Thanks in advance.
