OK, ffmpeg apparently doesn't like whatever format the audio is in on
this VOB.  Iso_dump reports it as "mpeg1 ^@^@ ( ) 16bit 48kHz 2Ch Not
specified 0" (yes, complete with two binary characters there transcribed
as ^@^@).  Nor does acidrip nor anything else.  Ffmpeg, for example,
identifies it as "MP2".  As a result what comes out is dead silence with
AcidRip just not bothering to write an audio track at all and ffmpeg
writing one out that translates to no sound.

The solution to this video mess is two-fold:
1.  To make clones of this DVD, I had to use "vobcopy -m" to mirror the
files.  At this point it's just a simple DVD burn away treating the
extracted files as I would any data DVD.  (An annoying problem with
Nautilus' DVD burning tools is that empty directories -- AUDIO_TS in
this case -- get ignored.  I imagine that some really picky DVD players
won't like that.)
2.  To turn the DVD into an AVI complete with audio I used "vobcopy" (no
"-m") to make a single, big VOB and then used ffmpeg on it.  The key is
that on the output I have to put "-acodec copy" to just copy the sound
in place.  When I do that, even Totem can play it!

So the solution is ugly (in traditional UNIX style), but it now works
and I can actually send my wedding video to my relatives and friends
around the world as well as make copies for local friends and relatives.
