Help, gray parts!

Hi, I've been using AutoGK for a while and it's been perfect every time except for recently. I was trying to convert the "Grandma's Boy" dvd, which plays fine on my comp. I decrypted with dvd decrypter in file mode no problem. Upon converting to xvid, 700mb size, audio vbr 128kbps, the final result comes out with some gray sections. WHen these happen, the sound also goes ahead... What could this be? Thanks, Flaviu

I had a similar problems with another movie, it had to do with camera angles, does your video have multiple camera angles? How did you rip the movie?

Flaviu mentioned File mode. IFO mode will rip a single angle of a single PGC. If multi-angle is the problem, IFO is the solution.
