Comment(by Bill Southwell <chimera_god at yahoo.com>):

 Just a quick tip for all you guys with nVidia cards:

 We now have hardware acceleration in Linux for mpeg2, H.264,
 deinterlacing, and many more things if you have a recent card with the
 9300 or 9400 chipset.  Even older cards benefit from VDPAU in the nVidia
 beta drivers on nvnews.

 I am running driver 180.22 with Myth SVN 19564 and r19, and am playing
 1080i high def from HD Theater on a Quadro 1600m (without HW H.264) and
 2GHz CPU, running at ~33%.  This ran at 66% with CPU+ and CPU++ profiles,
 and halted every three seconds, but no more.  No CoreAVC decoder or
 anything else needed.

 You have to compile Myth with --enable-vdpau and --enable-proc-opt then in
 Setup|Setup|TVSettings|Playback|{3rdScreen} and Add New.  Name your new
 profile VDPAU and Add New Entry, Match Criteria '>', Decoder 'Nvidia VDPAU
 Acceleration', Max CPUs is the # of cores+1, Next. Primary Deinterlace is
 'Bob (2x, HW)' (Advanced2x is blurry on pans) and Fallback is 'Advanced
 (1x, HW)', Finish.  On the next page make sure 'Use HW Accel for Live
 Preview' is checked, and go back through Playback to make sure VDPAU is
 selected, then Bob's your uncle.

 Enjoy VDPAU hardware acceleration!
