The audio on a DVD does not necessarily start at the same time as the 
video. Users of such Windows tools as DGIndex know this, as it puts the 
audio delay value right in the name of the audio tracks are they are 
demuxed. So no, no need to GUESS the delay, just a matter of determining 
what the delay value is.
