Very infrequently -- no more than once every couple of months -- I set up to record a program on channel 204 (DIY Network) but instead get channel 20 (one of the religious channels). I always thought that somehow Comcast was messing up over night, since that's when it tended to happen.
This afternoon I caught it in the act. I noticed the Replay was recording and turned the TV on to see what it was. The program I saw was one of the religious channels and not the DIY network that I expected to see. I called Comcast and the nice fellow checked his end, and reset my cable box. But it was still on channel 20. Since I didn't want the program on channel 20 recorded I stopped it, thinking that I'd change to channel 20 and back to 204. But 204 was there when I hit stop. How it got there I don't know, but I'm suspicious about this only happening on those occasions when I want to record channel 204 and get 20 instead. Again, this doesn't happen all the time.
Has anyone ever seen this behavior, where the first two digits of the channel to change to reach the cable box but the third digit does not?
