AFAIK, yes.

Yes. This isn't as fast as rending the XvMC surface directly,
but my 6200 can handle 1080i, so long as I don't enable
the Composite extension in Xorg.

BTW This is currently broken in mythtv-vid. I haven't tracked
down the problem yet, but it was working before I merged in
the non-XvMC OpenGL renderer a couple months back.
