Windows 7 64 bit, latest MP version -- I've so far bought 3 remotes advertised as MCE remotes. So far, even though I chose Microsoft MCE Remote in the Configuration, almost none of the buttons work. Mostly I play back movies from my NAS, which play beautifully (better than PCH boxes ever have). None of the the remotes' "Play" "Stop" "Pause" or other playback-related buttons work. Some buttons for other functions do work. I have to use my mouse to select from the pop up menu at the top. Does anyone have any ideas as to what I'm missing?
