I'm trying to rip my copy of 'Monster House' to itunes so that I can play it on my ipod. I've tried Handbrake, and Mactheripper and neither will work. If I use Handbrake it only rips the first few seconds of video, if I use Mactheripper it gets to the very end and says 'Bad Sector' and quits. There are no scratches on the disc. It is brand new.
