i just copied a movie and copied the entire thing, with all the extras, subtitles, etc...but i noticed that towards the middle, the movie starts to freeze up a lot, i mean, i have to skip a few chapters for it to enjoy watching it w/out freezing. are there ways to avoid this? would i have to exclude all the extras? or maybe change the writing speed, if there's a way? the way i copied it was by using DVD Decrypter and DVD Shrink 3.2. i'm running win xp. please help!
