3FG, if you're still around I have a follow on question/problem. I decided to program an all on/off macro on the pip on/off key as you suggested and it just doesn't work. I've followed the sequence about 5 times using both the instructions you gave and those for 9xx commands on the hifi-remote site which are essentially the same. Does something need need to be unlocked in order to change keys that aren't typically intended to be changed? Actually I'd rather put the macro the "help" key since its easier to hit and does nothing at all on my setup, but I'm not sure that key can have a macro. The JP1 site said that any key could be programmed with a macro except the device buttons and the setup button. That is a general statement that may not pertain 100% to a comcast remote. Any help would be appreciated.
