People use Mythtv in many different ways, the lack of HDCP support only
matters to those who have to deal with it.  Probably shouldn't say much
more than that it doesn't work on this list.

As far as the hardware itself is concerned, it has mixed reviews from what
I have found... it's apparently not the most stable device.

Better options are anything that uses UVC (http://www.ideasonboard.org/uvc/)
or an IP based system like

however I'm not sure multichannel audio is available from either of them
(you would think it could just pass it through without re-encoding).
