I am trying to program the AT&T uverse remote also. It is the S10-S3 black remote. I am trying to use the AT&T mode as I don't have uverse anymore. Whenever I go to program the keys, the software tells me that "Button already exisis." All I have programmed is the 1 button and trying to program the 2 button. I'm using the XBMC profile in the GUI. Any help would be appreciated. Also I am using the latest software and 2.6 firmware. PS I have tried programming one key. Then I went and pressed other keys on the remote and the one key I programmed in the gui lights up. Do All the keys on this remote use the same IR signal?
