I bought an Audio Authority Component Switcher and have used it with all my consoles on progressive scan (480p) and have not noticed a difference between the switcher and direct input into the TV. Next step is to try 720p and 1080i on my gf's 42" Sony HDTV, I expect similar results. A very high quality (automatic source select!) switcher IMHO, and makes gaming and DVD watching a lot easier.
