i ripped a dvd using smart ripper, then tried to encode the vobs to divx5.05 using FlaskMPEG. i'm doing the family guy series and parts of some episodes are in different vobs...flaskmpeg joins all the vobs together into one stream, but when i select a range to encode, it only encodes about 3 minutes of it...smartdvdripper also had the same results.

plz help.
