My 622 is connected to my main TV in the living room, but is also connected to a small TV in my office. I have a timer that records PTI and SportsCenter on ESPN every weekday. On a couple of occasions, one of my grandkids was in my office on the computer, and they changed the channel while I was recording. They had to go past the screen that told them they had to cancel the recording to do so but they didn't let that phase em! I think they now understand not to mess with my recording, but I was wondering if there was anyway to protect that timer so that someone with the TV2 remote can't cancel it on me.
