I've had this problem for a while, but wondered if anyone had a solution. I have a series 2 tivo with a Motorola cable box from Charter. This just came up all of a sudden and I have tried to switch cable boxes to see if it would correct with no luck. What is happening, is that on some higher channels(mostlly HBO type channels), when tivo changes channels the cable box will not stay on that channel. For example, if I change channel to HBO(channel 500), it will stay on that channel, but if I change channel to HBO2(channel 502), the cable box will continue to change channels...502,503,504.. until it gets to channel 540, in this case Showtime. This does not just happen to all channels, and not just on pay channels either. Can't tune into ION as well(channel 1xx). Has anyone see this and have any suggestions on fixing?
