You say the sound is 'late' - meaning that you see something happen
and then 5 or 6 seconds later you hear the sound.
If audio data had been lost/cut you would hear the soundeffect first
and then later see the action.
That sounds like several seconds of video frames were lost. This would
have the effect I describe above - you see something earlier than it
sounds because video has been lost.

Sounds like a frame dropping problem somehwere. 6 seconds would be
~150 frames.

What are you using to record? I can't say I've heard of any problems
with quality DV converters (Canopus is a good example).
I haven't heard of this problem before. Can you re-do the capture?
