I am a new avr 300 user in the States. I have connected a 1080i video source (direct tv hd tivo box) via component cables to the avr 300 which is connected via component cables to a Mitsubishi rear projection HD tv. On a 1080i broadcast (Discovery HD Theater) with a fair amount of white background, I am getting horizontal translucent lines. At times this degrades to the point where the TV "looses" the video feed and looks like it is resetting the video. I get some of the horizontal issues on a couple of other channels, but not to the same extent. The problem seems to be diminished when I drop down to 480p or 480i. I previously connected my video source directly to the TV and experienced none of these problems. Does anyone have experiences to report with the component in / out? Is it possible that the avr 300 doesn't have the bandwidth for a full 1080i signal? BTW...I can't get over the music quality with my 6 & 7 channel bi-amped to my older ads 1290's Thanks in advance for your thoughts!
