So I spoke a bit too soon. For whatever reason it started working in 
Myth, although I still can't get a good cat /dev/video1.  BUt I can't 
change the channel.  When I try and change the channel Mythfrontend 
reports an error and the exits back to the menu.  When I go back into 
livetv it is on the same original channel and there is no audio.  If I 
exit out and go back in I get audio back, but still can;t change the 
channel.
