I plan on using component with my HR20 b/c I have had issues with Directv's HDMI connections.
I don't have any other HDMI sources to test(been waiting for this BluRay HD-DVD fiasco to settle out or just go with an new OPPO).. I haven't tried a direct connection to the TV--good idea, but I couldn't leave it like that and have the 2808 as the switcher.
I am assuming if I have the STB(HR20) set to either 1080i or 720p output resolution, that would be a set resolution. How does the Denon need to be set to just pass this through?
Another thought, I have the HR20 menu set to 480i,480p, 720p, 1080i. I did this because I wanted my analog out to be active for recording to DVD and maybe this is what causing the changes/video sync dropouts during broadcast.
