My HDTV system , until recently, consited of 1 HDTV and HD Sources: Blu Ray , Apple TV, Xbox 360 and Xbox 360. I connected using HDMI switch because I wanted the HDMI quality. Now I just got a second HDTV on a "black friday" specail and want to share the HD sources with the second HDTV. I just installed a HDMI matrix switch, with 4 inputs and 2 outputs and it allows me to route all 4 sources to both TV at will. The guys at the Electronics store had no clue how to do this via HDMI ( i guess because not many have 2 HDTV yet). But where there is will, there is a way. Hope this helps.
