I just got a series 2 dual tuner Tivo and my cable company is Charter Communications in Pasadena. Everything is set up correctly, but for some reason, some (not all) of the channels are not showing the right video. Example: channel 6 is supposed to be Nickelodeon, and when I enter that channel either by pressing the numbers or selecting it in the guide, the tivo info screen will say that I'm on channel 6, but the video will be from KTLA channle 5. And when I select cahnnel 5, it's also something different. But some channels are correct. What's happening?
