I have duped a HD program from a Comcast Motorola 6412 PVR to my E80H via S-video (480i) and burned it to a DVD-R in the SP mode. IMO it was close to a pre-recorded DVD in video quality (played back on a Panasonic 42PA25U plasma in zoom mode), but of course only 2.0 was recorded in audio. So while you can't archive HD material yet, except on a HD-VCR recorder (good luck), you can get some very good lucking copies doing as I did.
