I've seen something like this before. When we had Comcast, a tech came out to replace our downstairs STB. He plugged it in, turned it on and went outside to his van. I turned on TWC, and to my surprise, was seeing STAR #22434 (New Ken/Allegheny Valley,) while all my other TV's showed #22438 (Penn Hills). I turned to Weatherscan and was getting the Allegheny Valley Weatherscan, too. Then he came back in, ran through the diagnostics menu, reprogrammed it, entered a long number, which set it to receive the feed from the Penn Hills headend, and thus, I was seeing the right STAR again. Very interesting!
