Very good points--it's not 1999, anymore.  And thanks for the follow-up 
on my desktop manager guesses.

One additional point, though--some Window Managers used by Desktop 
Environments may impact Myth usage.  (Where "some" is read as 
"Compiz"--its use of OpenGL may cause issues with OpenGL/VDPAU/... in 
Myth. ;)  But note that you should be able to change the Window Manager 
used within the Desktop Environment.  If you don't see issues with it, 
using such a Window Manager is not a problem, but if you do, try 
switching Window Managers (even within the Desktop Environment).
