ok so I am backing up my DVDs to my computer so I dont have to go bring all 40 of my dvds back and forth to school with me every time i come home. i use handbrake, but sometimes it will only rip like 15 minutes of the movie. so i ripped the dvds using mactheripper first. then i converted that folder with handbrake. it rips the whole movie, but cuts out the last 30 minutes of audio, and ive tried on 2 different dvds. when i open the dvd folder with vlc and dvd player, it plays fine, no problems whatsoever. anyone have any idea what the problem is?
