Charter has apparently published it's upcoming channel lineup too early -- both to companies like TiVo and to their own website.
So many channels will be wrong -- including HBO (SD and HD), BBC America (ditto), and numerous other channels. I don't know the full list, and even if I did it would probably be very, very long.
The printed material I have references May 20 as the channel lineup change, but it went active sometime in the past week -- we noticed it last night (May 10).
A work around, if you remember/can find the old channel number, is to set up a manual recording on the proper channel at the proper time. This is at least possible for the most important recordings. But in general this is a complete foul up by Charter.
