I sometimes get white lines at the top of my picture during commercials. Not all commercials and not all the time. It never happens on normal TV shows weather HD or not. I have a HR22 and a new Samsung 8000 LED TV. Because the commercials never last long enough for me to switch over to cable to see if it happens there, it makes it hard to test if its the TV or the HD box or the HDMI cable. I do notice that when on cable the commercials "fill" the screen but when on the HD box they get croped. I have the box set to original in the TV setting and aspect ratio set to 16:9 Does anyone else have this issue on commercials?
