i'm thinking about buying a new receiver, and am especially interested in these newer Denon and Rotel (etc..) receivers that have HDMI in/out connections.

I have a few questions:

1) do any of these upconvert *everything* to HDMI digital out, so that I can finally just run 1 cable to my TV?
2) do any input 1080p over component (and then pass that along to the HDMI out)?

I'm continuing to research various models, but it's difficult to decipher the cryptic (and sometimes innacurate) input/output specifiations.

Thanks!
