Hmm, I had thought about that, but can I have more than one set of
cables going from the STB to the HD-PVR? I need the components hooked
up for the regular HD channels. I suppose if it were possible I could
set up a third video source, but how would I tell Myth not to record
on tuner S-Video when tuner Component is in use?
