[mythtv-users] HDTV?

[Cory Papenfuss]

 	I would imagine that this would be useful to folks without XV then, no? 
Isn't the majority of the CPU power requirement for non-XV cards in the 
software scaling?  At the very least, it allows for non-scaled DVD resolutions, 
etc.  Does it use RANDR or just change the physical resolution (keeping the 
root X window and consequently the virtual resolution the same)?

Interesting...
