You can always go the route of HDMI --> HDMI2Component --> HD-PVR.

I have a HDMI to Component device that I'm using to connect to my TV
that has a broken HDMI port, but 2 Component Video ports.  None of these
small frontends do component video out any more.  Not using a cable box
or blueray, so don't know how the device reacts to "protected" content.
