Microsoft MCE remote into Pioneer RF100..?

Having trouble programming the Pioneer RF100 remote (came with my Pioneer SC-LX83 receiver) with the commands from my Microsoft MCE-remote..? I use the code learning mode, and the RF100 accepts every button, but when using it only sends the first touch of every button and then blocks that button. For instance, pressing "ch+" works when first pressed, but not when repeated. If I then press any other key, the "ch+" works again (once).

Anyone with a clue..?!?

Thanks...! A change in regedit and now it's ok..!!
