I've never tried splitting a component video, but I found one very
quickly for $10.
Of course, that may change how you drive your T.V.

Since the HD-PVR has a hardware encoder, it is doing the hardest work
of the entire process.
Decoding the H.264 stream (for display) is the second hardest part -
typically done via CPU or hardware assistance.
Saving the stream from USB to disk is not cpu intensive at all - it
would be a distant 10th (or more).
