For reasons nobody can explain, channels keep getting removed, then added back. Example, Recently ESPN1 and ESPN2 channels were removed. I called Tivo and they tell me (more-or-less), "Not our problem, call your cable company". I call comcast, they check their Comcast DVRs and tell me "Not our problem, our comcast DVRs have the correct lineup, contact Tivo.".... About 3-4 days later, ESPN channels are added back. This happens a few times a month; various different channels get removed, then get added back. Most of the time the channels that go missing are channels I don't watch, so I don't spend the time\effort to make (futile) phone calls. I watch ESPN, so I wasn't happy that it disappeared from the TiVo's channel lineup (on all 3 Tivos) for a few days. Anyone have any understanding why Tivo's Channel lineup is removing channels, then adding them back so fequently. And to be clear, there is a TiVo message each time the channels are being removed, and then added back.
