-    Notes:
 
-    Buttons on the remote are translated into equivalent button presses just
-    as if you were pressing them on the Gigabeat itself.
-    
-    We cannot tell if the hold is asserted on the remote. The Hold function on 
-    the remote is to block the output of the buttons changing.

-    Only one button can be sensed at a time. If another is pressed, the button
