Thanks Gonk.

I am quite pleased with the results of your brainstorming. I had considered bypassing the 990 for dvi/hdmi switching and going right to the splitter so your recommendation there aligns nicely. I did not know about the record outputs, and that sounds like a slick solution to my challenges on the xbox/cable inputs. I'll try and round up a reasonably priced HDMI cable today and let you know how it plays out. Thanks!
