i am using a imacs g3 500mhz and am ripping using mactheripper and then compressing using either dvd2onex or dvdremaster. somr of my dvds seem to pause at different points or some of the pauses freeze and the picture seems to shake or be jittery and then sometimes it will go on after a couple seconds sometimes not. some dvds turn out ok others turn out really bad and pause every few seconds. i use either verbatium or tdk dvd-r. what am i doing wrong? all my first dvds turned out great but latley they seem to not turn out so well so i dont know whats going on. any ideas?
