First wanted to say thanks to everyone for this wonderful source of information. I have been reading about a lot of the IR/Hex programming and just have a general question.
For remotes that can't "learn" the XMP IR codes is is possible to edit the Hex codes and then program them to use the modified codes?
Just curious before I ditch this older 2-way IR/RF whole home remote system.
And if you take the time to read or answer thanks!

Ordinary XMP signals can be represented by Pronto Hex. If your hardware doesn't learn any of the signals it will be hard to reconstruct. But if it can learn a few which work, then we may be able to guess the rest.
But why not just tell us what model of component needs the XMP? We may already know the codes.

I just don't want anyone to waste a ton of time on this because I am slowly coming to the realization that I don't think I can do what I want.
I am trying to control the Comcast X1 Pace "slave" box. I have this old distribution system call the BOCS Whole Home Video. It was a 3 channel SD coaxial modulator with a very robust 2-way RF/IR remote system. I already have remotes for every TV in my house so although I am not using it for video I thought I could still use it for control.
I have no problem learning codes in to the individual remotes but the main distribution hub won't learn the XMP codes. I tried last night to use IRTool to decode and encode clean signals but still no dice. I think I'm probably at a stopping point because the only way to get the codes in to the hub is learning through the IR window.
I just didn't know if there was some trick to make XMP codes look more like older IR codes and still work. I know....far fetched but can't hurt to ask right?
Thanks for the help.

Most IR protocols are fairly simple, with one on/off burst pair denoting a binary zero and a second burst pair representing a binary 1. XMP uses 16 different burst pairs to represent the hexadecimal digits 0x0 up to 0xF. Typically learning hardware assumes that the signal has only a few distinct burst pairs, and is confused by XMP. If learning is the only way to enter the IR signal, there probably isn't anything you can do.
