Indeed. I knew I was missing something, but just couldn't put my finger
on it. Obvious in hindsight.

But the UI is still 1920x1080x24x60 (perhaps /2) isn't it? There's no
bandwidth savings for still images are there? Isn't every pixel of that
1920x1080x12 sent 60 times a second regardless of whether it's changed

Well, for video, I send MPEG2 and VDPAU does the work.
But what I really want is the UI at 1920x1080 also, for the crispness of
it. But if I can't drive that over PCI, maybe the VDPAU makes it still
