Just got a new Arris AX013amn Xfinity X! set top box. Been playing around all day trying to program my MX 850 (I have had the software for more than 10 years) to control this thing. I got one code that will control some functions but the box wants me to "pair the remote". I updated the database. In the database under comcast there is an Xfinity code and that is the one that gives me partial control.

So, I have about given up on the 850 which is very sad because I love this remote (I have 2). Does URC make a remote that will control this box or is there something I am missing with 850? Thanks for your help.
