Uncommanded channel change?

Tivo Roamio basic, on Comcast.

Had an odd thing happen yesterday. I was watching live TV with the guide open and suddenly the screen went blank. After a couple moments, the message "searching for signal" popped up. Turns out that the Tivo had changed to channel 1, which is not checked in the channel list and is not in use on the Comcast system.

I changed it back to a valid channel and all was well..... mostly. For about a minute, the Tivo was very noticeably sluggish when scrolling through the guide or the NPL. I selected a recording, started playback and then went back to the NPL. From that point on, the response to menu scrolling became normal. No further issues have been noted.

It is probably unrelated, but the previous day Comcast was having serious signal issues that were resolved when they replaced an amplifier in the neighborhood. Some channels were missing (zero signal) and others were seriously pixelated (low signal). There are likely several very compromised recordings on the HD, but I was not playing any of them. And the live buffer had long ago been flushed unless there is a separate buffer for each tuner? If so, it is possible it switched to a tuner that had a previously corrupted buffer. Just a thought.

Anyone else notice anything like this?
