[mythtv-users] Configuring USB3 HDMI capture device non-HDCP source

>From a MythTV perspective, it should be treated as an analog capture
card since it uses the standard V4L2 raw video capture interface.  The
fact that the underlying video source is HDMI (e.g. a digital format)
as opposed to an analog video format such as NTSC is incidental.

That said, MythTV does make some assumptions with regards to the rates
at which the raw video capture interface will deliver video (see my
previous email).

The user might be able to reconfigure his video output at the cable
box to output at 1080p/30 rather than 1080p/60, at which point it
would likely work (although I wonder if perhaps lipsync will drift
over an extended period of recording).
