My 15" MBP is almost 2 years old. It won't play a particular DVD. The DVD plays fine in my Dell. I tried running VMFusion/Windows on the Mac, but it still wont play the DVD. The dvd drive on the Mac is a "Superdrive." The files on the DVD are: BUP, IFO, and VOB. Any ideas why this wont play? Can I get them to play?
