Hey folks, I'm using one of my HR-20s on through a Panasonic AX100U projector. I have the HR20 set to 'Native'. When watching an HD channel/program, all is well. However, when say a commercial comes on and the signal changes from HD to SD, I get a very thin, white line at the very top of the display. It kind of crawls and jitters. It will do this through entire programs that are not in HD, when watching on an HD channel. It what might be a related issue, I get a yellow thin line down the left side of the display when watching HD on NBC via the D* satellite fed local Milwaukee NBC stations. Any clues on what I could do to eliminate these? Thanks!
