Yes. It's just called RAGE internally. Table Tennis on the 360 was the first use, then GTA4 and Midnight Club LA

I have a HD cable PVR and a 720p HDTV. My SD feed is greatly improved by the HD PVR solely because it's a better specced box than the standard cable box provided by Virgin Media in the UK.

I believe it is the same here in the UK with the Sky (Fox) satellite boxes; the "HD Ready PVR" has far better decoders than the standard sat receivers on the SD channels as well as the superior digital out HDMI. [Shame its encumbered by the usual DRM]

So a phone poll asking users would be flawed if this is the case in the polls geographiocal catch area.
