Another MCE related post:
On a thread on TheGreenButton.com I found a nice enhancement to the Irremote.ini file that makes the Hauppauge remote control work with MCE. I do have some problems with the shortcuts that include special keys like Ctrl, Alt etc. (I have to press several times until it recognizes it) but it works.
Link is here and search for "IR.exe". One additional comment: delete the remarks like "; Up arrow" from Kenzos listing.
Update: updated the link
