I've just noticed that this xorg.conf file does NOT have a line:

	Option "XcmvUsesTextures" "True/False"

I also notice that Dan Seddon just posted a comment that this option 
should be set to "TRUE" (for Nvidia chipsets at least: see "XvMC with 
Nvidia 7676 no change in CPU usage?") while the mythv wiki page dealing 
with Xvmc says to set it to "FALSE"

So anyone want to wage into the battle, urging a setting of 'whatever'?
