The highest video performer that is out now would absolutely have to be the Onkyo TX-SR805, because it is a HDMI 1.3 machine (it is the nicest one available at the moment). Denon, Sherwood, and Pioneer are all expected to have released comparably featured receivers by year's end. It can also be expected that Yamaha will soon be doing the same. The Onkyo TX-SR805 is the beefiest (heavy at 50 pounds, means big power supply and reserve power) of it's competitors, and the most advanced with HDMI 1.3 and the latest Audyssey auto-setup program.

if video is key, run it directly to the display.
There should be no video degradation by sending video through the receiver via HDMI, unless the receiver is faulty. An added plus of using HDMI switching on these receivers is the process the audio off of HDMI if it is present from a source like a Satelite box, Blu-ray player, HD DVD player, or upconverting DVD player.
NAD and Outlaw currently have no HDMI features on their receivers.
