If you find something let us know. Not true, the Intel driver also supports it. I don't believe that the radeon driver does currently, but XvMC is only useful for mpeg2 content, which limits it somewhat. > > > 3) A second connector off the same card for feeding a smaller > > > secondary monitor at the same time. > > > 4) Some sort of power save mode...

Not sure about that actually... VIA has released docs, but we don't have drm support at this point as I still don't have VIA hardware to work on. > For tuners there is the HDHomerun.

Mostly... I'm actually ahead of the penguins on ATI support right now.
