Have a TiVo HD with a multi-stream cable card from Comcast.
Prior to Sunday, everything was fine.
On Sunday I called Comcast to add HBO to my cable lineup. Works fine on TV upstairs, not so on TiVo. I "add" the channels to my lineup through setup menu (so they show in the guide) and restart the TiVo.
HBO works after restart, but on Monday, I realize that some of my other HD channels are not coming in. Locals are fine, HBO is fine, but every other HD channel is a black screen, no sound. Again, everything is fine upstairs.
I called Comcast, they had me restart again (I'd already done this a few times). Still no joy. The rep schedules me for a tech to come out.
I refuse to believe there's nothing more they can do...send some sort of signal to the cable card or something...
Does anyone have any suggestions about what I can do to get this working? I don't want to break it more than it already is :-(
