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.

Ok, did some checking on the interwebs and found that code 203 will control the most used buttons. There is no voice control (no biggie) but it not asking me to pair. Cant control power but not going to get real concerned about that for now. If anybody knows a power code or if URC has something that will do better would appreciate the feedback.
