Another alternative, avoiding having to pay for the AC-3 plug-in, would be
to bring the dvd into TDA, which will save the recording to your hard drive
as an .mpg file, then do the precision editing with Womble, which (as OP
will know) is extremely precise.
Then bring the edited files into TDA and author as a DVD. Without the
plug-in, TDA won't play the AC-3 sound, but it will pass it through without
any problems.
Because (unlike Nero, for instance) it doesn't re-encode incoming files, I
don't think that passing them through TDA twice in this way will cause any
degradation - and it is very quick and intuitive to use. (I don't think I've
needed to look at the instructions since I got it!)
