yes, h.264, VC-1, MPEG2, and MPEG-1

Add deinterlacing, noise reduction,

Yeah!

There is an API for compositing sub-picture, on-screen display, and
other UI elements.

That should help.

hmmm, I'm not sure what you mean exactly. I guess not. After all, that's
the goal of HW acceleration.

The internal player uses ffmpeg libraries.

NVIDIA has already patched ffmpeg (as well as mplayer) and associated
libs to work with its API.

If MythTV picks up the right code, as it wants to ship all that by
itself (I always wondred why), all should come to MythTV in good time
without much effort (I've been known to be wrong and I am no MythTV
dev).

That should certainly help the undecided.
