Okay, on the advice of a terrific guy in the Mandriva forums, I 
uninstalled and reinstalled all of the nvidia drivers.  Everything is 
now working as it did prior to my yanking out pulseaudio.

So, how can I get audio fromMythTV's frontend?

As has been stated before, pulseaudio is disabled in Mandriva Control 
Center and all of my other media players produce audio just fine.  
What's special about MythTV? How does MythTV read audio from these mpeg 
files?  Why could it be broke and what do I need to do to fix it?

Thanks.

Mark
