I tryed to make a dvd with short films with dvdit. After encoding with TMPGEnc and making a menu the file size went up to 9,3GB. I used output size of 10GB and dolby digital(128-stereo). After creating a DVD folder the it was only 4,3GB big and fitts on a dvd, but the video was slower then the sound(after 20 min it was 1 min behind).
What am I doing wrong?

Thanks!
