You aren't going to see black-box HDMI-in for DRM reasons.  Even
HDMI-out for over-the-air digital signals is potentially subject to DRM
(see: broadcast flag)

It looks like the only way to capture HD TV in a F/LOSS manner is to use
the Hauppauge HD-PVR.  It captures HD signals from the composite ports
on your cable box/digital source and outputs them over USB to H264.
While the captured signal is not the native digital, I find the results
are more than satisfactory for TV watching.

The upcoming mythtv 0.22 has support for this device along with VDPAU to
accelerate HD playback on newer Nvidia graphics cards.  The upcoming
mythbuntu 9.10 doesn't look to go this far, but there are deb repositories:

http://www.avenard.org/media/Ubuntu_Repository/Ubuntu_Repository.html

http://debian-multimedia.org/

that will let you build your own deb-PVR fairly easily.
