Thanks for the link. I had thought of overscan issues and I might play with settings on the projector, if possible, to see how this might affect it. I have seen a single pixel line (on the top or bottom of the screen on some channels) of random colours on certain channels very rarely. However, I don't currently believe this is the issue I'm seeing with regard to MC HD.
After re-reading my previous post, I realize I was unclear what I meant by single line of pixelization. I didn't mean a single scan line, I should have said a single row containing multiple scan lines of pixelated (blocky but related to the image colours - not random) blocks along the bottom of the screen.
The image is coming from the Gateway portal (set to 1080i and 720p so it sends the original signal through) direct to the projector through a hdmi cable. Audio only goes to the receiver through an optical cable. The problem seems to be happening with multiple movies, both watching live or playing back recordings as long as the movie is 16:9.
