Mark's fix patches are built in the VDPAU patches, so don't apply
those patches again (it would fail anyway)

Does the patch apply cleanly ?

I compile mythtv with the following command:
CFLAGS="-g -O2 -fPIC -DPIC" ./configure --prefix=/usr --enable-lirc
--enable-audio-alsa \
	--enable-audio-oss --enable-audio-jack --enable-audio-arts --enable-dvb \
	--enable-ivtv --enable-firewire --enable-joystick-menu \
	--enable-opengl-vsync --with-bindings=perl --enable-opengl-video \
	--enable-ffmpeg-pthreads --enable-vdpau \
        --compile-type=profile --enable-xvmc --enable-xvmc-vld
--enable-xvmc-pro --enable-glx-procaddrarb --enable-libfaad
--enable-libfaac --enable-libmp3lame --enable-libx264 --enable-libxvid
--enable-libfftw3

Looks like your nvidia drivers (minimum 180.22) aren't properly installed.
See the line:
VDPAU support : no

that's because it didn't find the relevant libraries and headers.

Looks like it doesn't build properly in the even VDPAU libraries
aren't found... The VDPAU code shouldn't have been compiled at all ...

I noticed some error in trunk too if you requested VDPAU and it wasn't
available, it doesn't build cleanly either...

libvdpau.so and the vdpau headers *MUST* be installed
