Has anyone ever used one of these? It's not cheap but says it converts everything to High Definition. http://www.dvdo.com/pro/pro_isvp20.php

There are a bunch of A-V Receivers now that do the same thing, for less $. All it's doing is up-converting to HDMI. There's a big difference between an up-converted signal and a true hi-def signal. It may well be a top-quality piece of hardware, but at that price it's not on my list.

What's more, this particular model only has 2 sets of inputs. That's pretty limiting.

Here's an example of a wet-dream receiver (at least for me):

This thing does everything except make the popcorn.
