Yesterday Comcast changed the HD channel line-up - and they did it in a way that requires changes to some season passes.
1) Check your season passes for any of the channels below - basically all the HD channels except the networks. If they aren't pointing at the correct channel number, delete and re-enter the season pass.
2) If the new channel #'s are not in your guide correctly, you may need to re-run guided set-up. According to Tivo, Comcast didn't broadcast the channel changes "properly". Often you'll recieve messages that the channel line-up has changed. These changes didn't broadcast these messages. Guided Set-up Instructions
At one customer, this resolved it, at another, that step was not even required.
3) If that doesn't work, you can either call Tivo @ 877-367-8486 or Ambleside (this is not warranty work - charges will apply for Ambleside handling and followup with Tivo or Comcast.) I'd expect they'll clean it up in a few days as it probably effected all of Tivo's employees too.
On the good news side, Tivo recently released a new software version that enabled multi-room viewing, tivo-to-go and hard drive expansion. Your tivo can also display pictures, home movies, music and lots of other stuff - click here.
Note: The below channel changes will occur in all Bay Area Comcast cable systems except those neighborhoods in Hayward, San Leandro, San Lorenzo, Half Moon Bay, Saratoga, Sunnyvale, Milpitas, Los Gatos, Santa Rosa and Mendocino County where our new advanced digital network is not yet in place.
