Having a peculiar issue that I'd love some help with. I have a Tivo Series 2, using a Motorola Fios box to decode Fios digital television. Recording works fine, no problems there. When I'm watching live TV, I can use the number pad on my remote to enter a new channel and it will switch, but I can't use the Channel up/down buttons. They register on the TiVo (that is, the light on the front flashes to show that it "saw" the remote), but it seems not to be issuing a command to the Fios box.
The Fios box remote works fine to change channels.
Is this somehow not a supported feature? Is there something else I'm doing wrong? I went through the remote setup process again, but that seems to be focused just on plugging in a specific channel number, not on surfing up/down.
Any ideas would be greatly appreciate. Thanks!
