Right.  I found the link to the config file referenced earlier in this


There's two monitor definitions (VGA and TVOUT), two device definitions
(deviceVGA and device TVOUT), and of course two screen definitions
(screenVGA and screenTVOUT).  How would one enable XvMC on the TV output,
but not the VGA?  Is it just the ordering of the definitions which is
important?  If so, which definition is the key - the monitor, the device,
or the screen?
