Everyday you learn something new! It’s a while that I make my personal DVDs from an analog source with no audio problem.

Recently I learned about the audio delays in AC3 and know nothing about them. I want to learn more about them. My questions are:

1) Does audio delay exist in a standalone ac3 file or is it in the muxed vob file only?
2) What is audio delay? Are there physical silence in the ac3 file or is it just a flag and a number?
3) Why on earth they put audio delays on commercial DVDs anyway?
4) When I have a wav file and encode it to ac3 in Scenarist, it gives an audio
delay of 0. Should I change anything?
