Thanks for replying Park. I agree that at least the MCE remote functionality works. But I would like to do some more remote customisation, and learning new IR commands is the only way I can do it, without repurposing existing MCE IR commands. As it is I have repurposed the "DVD Menu" command to open and close the Blu-ray drive on my HTPC, as I'm playing Blu-rays and DVDs through MC, so get away without having that function . . . I think.
While we could try using yet another application or hardware such as Girder to solve the problem Imugli, the IR command learning feature in MC should work, and should learn commands outside its know set, particularly when the IR command is being used to launch an external application as in my case. (I use an external application to open and close the optical drive.) A learning remote control will learn any IR command, within some restrictions, for use in controlling multiple devices. It would seem that MC should also be able to do that, and hence make use of the learned commands on a learning remote.
In the case of my Harmony remote, I can generate keyboard like IR commands such as ALT-1 to 9, Win+{key} commands and so on, as supported by the "MC HTPC SE - Microsoft Media Center PC (Windows Media Center SE)" device profile. It can also learn IR commands from any other remote. It would be great if I could use those IR commands and assign MC Core Commands to them, or run other external programs.
I think the functionality is broken, or just incomplete, or poorly scoped and designed in the first place.
It would be nice if J River would fix it.
