A set of debug level logs would be a good start...
Run the MP Watchdog tool, select the first option, hit the 'Proceed' button (which will start MP).
After MP starts operate the -/+ keys, then the vol up/down (speaker icon) keys and finally the MCE remote vol up/down buttons. Then close MP, and the Watchdog tool should create a zip file with all the logs in it. Upload that here.
