AC3 Delay Time?? (jdobbs)

[nad]

Ok, I just made my first successful DVD backup using the Ocean's 11 DVD.

I noticed that the audio was very slighty a bit off. It may be just me. I don't know.. but it think it is slightly off.

My AC3 track had an 83ms delay on it. Was I supposed to remove this delay with some tool??? Or is that delay supposed to be there?

Because if anything is causing this slight bit of asynchronization, it is probably because of that 83ms delay.

Use AC3 Delay Corrector to fix the delay before authoring. It's freeware:

Should the delay time on an AC3 track always be removed???

I always remove it unless, of course, it is 0ms (it often is). It is a way to ensure your audio/video is in perfect sync. Actually when you get down under 50ms (1/20th second) it can be pretty hard to tell.
