B: CGMS-A is definitely being put out by STBs. There have been numerous reports of recordings blocked, locked, or encrypted when Media Center records (or attempts to record) premium channels or even AMC at times from the composite or S-Video STB connections.
C: Hauppauge has never built any DRM into any of it's drivers yet. All restrictions have come from the recording software application - generally Media Center.
A: Media Center should treat the HD-PVR like it does any STB capture device. Pick channels from an EPG and use a Blaster to control the STB. In place of a typical hardware mpeg capture card it would use the HD-PVR. Support would only be needed in the form of an upgrade to recognise the HD-PVR the same way it recognises any new capture card and video decoders for playback/viewing. It's not recording "Component", it's recording a .ts stream and it may just record it the same way it records from the HDHomerun.
While many have speculated that there is no way to add CGMS-A to Component connections, I sure wouldn't bet the farm on it. If it can be added to composite video, then it can be present on component video. The "Y" cable contains standard video + sync, albeit at potentially higher frequencies. A 'scope of the signal ought to look exactly like Composite luminance, just at a different horizontal range setting.
This might actually be partially testable.
Pick a channel sure to be restricted. (HBO?)
Set the STB to 480i output.
Connect the Y (Green) cable to the composite input of your capture card. (It'll be in Black and White)
Attempt to record with Media Center.
Whether any potential flag gets carried through when Component is converted to H264: I couldn't guess.
