I wasn't sure if this was an HR-20 or NBC-HD feed issue, but since last Thursday or so (the best I can guess), I've been having a problem with the picture on the MPEG-2 feed of NBC-HD (Ch. 82). There is a band across the top of the picture (about 5-10%) that discolors whatever is at the top of the screen. Red, for example, shows up as a bluish/purplish color while blue shows up as a greenish color. It only happens on NBC-HD (MPEG-2 feed), all other HD channels look normal. It happens on HD as well as SD programming and occurs on component video as well as HDMI on my plasma and DLP projector respectivley. A red button reset had no effect, so I'm thinking this is a feed problem. Quite honestly though, I'm surprised that they haven't corrected this problem already. The last normal NBC-HD recording I have is Medium from last Wednesday. It's still happening right now on Law & Order. Thanks for any feedback.
