Thanks ozzlo, I searched the reg and did not find any trace of the firefox extension. I also checked dmx and found all of the references to it only by the dell media experience program.
I did try another idea, defining a shortcut key. I noticed that when checking the properties for a shortcut, if you are in the shortcut key field and press the play button, it shows up as Ctrl + Alt + G. This however did not work. Then I tried something off the wall, Ctrl - Shft - Alt + F12. This did work. Not that I would want this combination, but it did prove that Media Player would launch through a shortcut key.
I reset the shortcut key for media player to Ctrl + Alt + G using the play button to enter the key combination. Thinking something is capturing that play button, I uninstalled media experience, and the quickset program and rebooted. Still no luck I tried pressing the Ctrl + Alt + G keys instead of the play button, this did indeed launch the player.
So Windows recognizes the play button as a Ctrl + Alt + G key press, but something must be intercepting it before it can launch the player, I just don't know what.
If anyone else does get this to work on a 9200 I would like to know. Maybe this trick won't work on a 9200, but if someone does get it to work, then maybe it is my configuration and I can try it the next time I wipe and reload.
