Keyboard Keys are NOT remote codes.
I'm quite aware of that Brian. And yet, changing a keyboard setting, the "Media Key Mode", changed how the Remote Control functionality worked in MC, disabling some primary buttons.
You may not be aware that the Harmony "Media Center SE" profile that I am using on my Harmony 880 remote names many of the additional commands Alt+0, Ctrl+Alt+U, etc. I don't care what the actual IR Code used is, just that I can assign one to a button on my Harmony, and MC can learn that IR Code, so that I can assign an MCC Command to that IR Code.
Get a FLIRC. <snip> Or, I guess use Event Ghost to send arbitrary key sequences based on any remote key. <shrug>
I have no interest in adding another layer to the control of MC. The MC Remote Control functionality is simple and straight forward, in theory. Get a remote, pick a button with an assigned IR Code, MC will either already know that IR Code and have a function assigned to it, or can learn the IR Code and have an MCC Command assigned to it, or the existing assigned Command can be changed to what ever is required. MC even supports a sequence of Commands being assigned to one IR Code, like a small macro. Unfortunately, there is very little documentation and no visibility of what MC is doing internally, so users have to work blind if they want to actually make use of the ample functionality that is already there.
I don't expect MC to ever truly support all IR remote sequences/codes. Perhaps I'm wrong.
Perhaps. However, both Jim and Hendrik keep insisting that MC can learn any IR Code, and that appears to not be the case. If it was I could add the dozen or so commands that I want to use to my Harmony remote, and all would be good. As MC supports an RC6 MCE remote, it should be able to learn all the commands from my Harmony, using the "Media Center SE" profile. In fact, in order to use the Blaster functionality, MC needs to be able to learn IR Codes from various devices, so that it can forward them to those devices.
Of course, I am using a Logitech keyboard with my HTPC, and I haven't tried reconfiguring, turning off or removing the software associated with that yet. It may be part of the problem, preventing IR Codes from being learned. Or it could even be my Inteset CIR Receiver can't see certain IR Codes, although that seems unlikely. So I still have some things to check.
I guess I am just pointing out a niggling issue with MC, that prevents me from using it with my Harmony remote as I wish. Particularly as it is claimed MC can do what I need. So I am working through the possible issues, at my own pace, and documenting what I find. That is all.
