I have a Series 2 TiVo that is about a year and a half old. It had worked fine until about a month ago. The electricity went out due to a neighborhood outage. When it came back on I rebooted the TiVo. A few days later I noticed that I could only record on one tuner at a time. Also if I tried to record a program and then switched to tuner 2 and then tried to change channels it would tell me that if I changed channels it would stop the recording presently going on, as if I was still on the other tuner.

I tried resetting the channels (I have a cable box and only the channels in the channel list that are marked "box" have a check mark next to them. I checked the cable connected to the TiVo. Any suggestions?
