I have Charter cable with two cable cards and a tuning adapter. It works pretty well a majority of the time. I've been having an intermittent problem that has gotten worse the past few days.
Basically, I'll be watching a recording with nothing currently being recorded on the TiVo, and suddenly it looks like I'm repeatedly hitting the guide and live TV button over and over again. The guide will pop up and then shortly thereafter my program will be interrupted and it will go to live TV. It will then flash the guide and then the progress par over and over in sequence.
When this happens, my place in the recording is lost and it starts from the beginning when I go back to it.
Sometimes it will happen rapidly and other times slowly. When it happens slowly, I can sometimes prevent it from interrupting playback by hitting clear repeatedly.
Going to other menus doesn't make a difference - it's not really an issue that only occurs in playback, but it is the most annoying there since it causes my place in the show to be lost.
Rebooting the TiVo doesn't always help. Same for the tuning adapter. In fact, the symptoms continue if I actually unplug the tuning adapter.
I am using a harmony 880 remote and have watched carefully and actually attempted to block it to see if it is coming from the remote. It doesn't seem to be.
So far it doesn't seem to have interrupted any recordings. Probably because the behavior would seemingly result in simply switching to the show being recorded.
What can I do to troubleshoot this odd behavior?
