Well I got myself a HD PVR 2 Gaming Edition and can confirm the driver 
works.

It's clearly a leak of the alpha driver since some things are clearly 
not finished or tested and the debugging is very verbose. It's easy to 
get it to segfault since many error conditions aren't checked - for 
example passing a filename of a file that isn't writeable will segfault 
the test app.

A couple of things that had me puzzled you need vim installed to get it 
to compile since the build uses the xxd utility which on my Gentoo 
system is provided by app-editors/vim-core. Second it seems to capture 
from the HDMI port you need both the input and output HDMI connectors on 
the HD PVR2 connected to something otherwise the test app fails with a 
No input connected error. Even with it connected the pass through 
doesn't seem to work but the capture does work.
