OK, one of the Windows machines was jacked and a reboot fixed the audio 
on the other.  Thus now I can play the original MythTV *.mpg recordings 
on Windows.  However when transcoding with nuvexport-dvd (or any other 
format0, I still get no audio.  VLC shows one audio track as a *.mpga 
file and shows frames being decoded but no audio.  mplayer shows no 
audio.  Any ideas on how to get this working?
