Comcast Xfinity remotes only contain TV-specific codes

[Rexypoo]

The XR11 and XR15 remote codes in the Cable_Boxes/Xfinity path appear to only contain television codes, which are configured for a specific television during first time setup.

I did some research, and it looks like Xfinity remotes only use IR during first-time setup. After setup it switches to an RF signal* to control the cable box.

The fix is actually fairly straightforward: to scan Xfinity IR codes first you have to unpair the remote from the cable box, and then it will broadcast IR.

As such, I've recorded a proper set of XR11 IR codes (#319), but I don't have an XR15 remote to test.

Things to note about unpaired remotes:

• You can easily re-pair the remote by either hitting the voice button, or by hitting the "Xfinity" button, going to the gear menu and scrolling through the options to the "remote" section.
• TV power / volume / mute send codes that my TV doesn't recognize. TV controls are configured after setup.
• At least on the XR11 remote, the setup button doesn't broadcast any IR code.
• Be careful testing the "D" key. In most cases it may look like it does nothing, but on the recordings menu I think it's supposed to delete recordings.
• The voice control button doesn't do anything useful, it just pulls up a prompt to pair the remote.

*Some sources on the web suggest the Xfinity remotes use a 2.4 GHz ZigBee protocol, in case anyone's interested.

Thank you for addressing a portion of it. Will leave this open.
