I think now vdr (and xine) should be able to use vdpau if...

...you apply this patch to the multimedia/libxine port (at least
until it has been committed),

or the xz(1) compressed version:

and then make sure libxine is rebuilt with the VDPAU knob on.
(You can manually invoke the config dialog with `make config' in
the port dir.)  And if you already build vdr and its plugins you
may need to rebuild at least the multimedia/vdr-plugin-xineliboutput
port too.

And in case anyone is wondering, vdpau is a feature of newer
nvidia graphics cards that can offload major parts of mpeg/h264/vc1
video decoding onto the gpu so those can be played with less cpu
load.  (Or even at all like often with hd video on `smaller' cpus.)
