3.4.79ish.  Followed all the instructions on installing “binary blob”
drivers and fbturbo and finally VDPAU.

cross compiling.  I only compiled libs programs and yes it took forever.
There was a syntax error in the ffmpeg portion.  I found a patch for it in
the ffmpeg forums and then it compiled ok.  In fact everything compiled ok.

play back to vdpau slim, audio to the hdmi device and went to play back a
recording.  I chose a very low file for my first test.  A recording of “It
takes a thief”.  After some crackling, it played.  Yep it played.  Not
perfectly.  Not usably, but it played.  Oddly it played too fast as if I
had chosen to play it back at maybe 1.5 times normal.  There was some video
tearing but the VDPAU stuff is still very new, perhaps that will change.  I
can’t get the OSD to appear, not sure why.  Choosing OpenGL for the painter
gives a black screen (I fell back to qt).  Oh and playback continued with
30-50 percent idle processor.  Audio seems to be sketchy, I will try it
with the non-hdmi connector to see if that makes a difference.

Attempts to playback recordings from my HDPVR resulted in a ball of
scrambled pixels in the center of the screen.

Fantastic work.

The low power arm market is pretty full. I see a hackberry is US$65 plus
case, power supply, maybe needs remote control hardware too?

For $100 you can get an Amazon FireTV, sideload XBMC, use the pvr client
and also have access to Netflix, Amazon prime, and all the other goodies.

Not trying to detract from your efforts, just saying ...
