I'm back! First, forgive my manners and thank you for all the help you've provided. Had a couple of months using the programmed remote and it's been pretty good but I do have three questions:
1. Is there a way to "lock" the remote with a special numeric code so that wifey dearest doesn't jab at the wrong buttons and screw up the programming? She has some how unprogrammed it a couple of times.
2. Everything seems to work ok except for one thing. Pressing any button on the numeric keypad will UN-sync the remote and give me a blue screen "No Signal!" warning. Have to then press the Orange button to re-engage the Xfinity tuner to the last channel it was on. So if she knows that channel 845 is something she watches regularly, rather than trying to bring up the guide (that is flaky) and scrolling thru 100's of channels, she tries to punch in 845 and the screen goes blue.
3. As noted above in #2, pressing the guide button doesn't bring up the guide. It was working when first programmed but then it stops working.
Thanks again for the help.
