811 HD comonent is great on my Mits
My Mitsubishi 55711 wide screen has beautiful HD via the component input. Also handles the OTA very good, and then their is Comcast cable also is on another input. Comcast has never been acceptable, but have it by way of home association. Have Sat, OTA, Cable, DVD, Tivo, vcr, camera, etc., running through the Mits.
Component output from 811 is very good.
