Backing up the messengers

i backed up the messengers with 3126 and movie came out great as an iso image but tried to do full disk previews came out perfect but movie came out at real low quality used nero and instant copy they both came out perfect this is the first time this has happened iso image always was perfect but when i got a 3gig file i was suspicious and was poor quality has anybody tried this movie yet

People using dvd shrink stated they had no problems, I used dvd next copy and had no problems, I also noticed one click can do this title with ease too. :smiley:
