vf + vdpau generally don't work. If you're looking for deinterlacing, the
latest mesa (10.2-rc1) should have support for it (via DEINTERLACE_TEMPORAL),
you can turn it on with "mplayer -vo vdpau:deint=3" IIRC. I do recall the black
bars being weird when you do that though, but that is an mplayer-only artifact,
apparently.
Note that VDPAU is Video Decoding + Presentation. So if you're seeing high cpu
usage, it's probably just doing the presentation and not the decoding (for
which you don't need firmware, btw). Make sure you're using the appropriate
codec (e.g. -vc ffh264vdpau). See
