ok i have two dvd compliant mpeg-2 dvd rips, i trid merging them with TMPGenc but the audio got way aout of snyc on the second half of the movie. when played each on their own the audio is perfectly in sync. im wondering if i import both clips into a program, such as dvd moviefactory for example, will it play seemlessly? if no, is there a way i can make it so? an even better answer would be how to put these two mpegs together properly so that the audio stays in sync...thanks!
