Thanks, that's borne out by the evidence that I have. I currently have
the cablebox setup to up/down convert all video to 720p. All the
recordings that I make against the HD-PVR are 720p with Dolby 5.1
sound. In the future I may want to hybrid convert video to either 480p
or 720p but right now I'm happy with the way things are working.

Thank you very much, that's exactly what I want to know. In the past
when I have both SD and HD versions of the same programming, I had the
"only record in HD" flag set on some of my recording rules. As time
passes that rule is becomming superflous for me.

Thank you very much for the helpful information.
