How to get fiire cheif to work outside of linuxmce

Hey, I bought a fiire chief and for complicated reasons (mostly hardware problems), I can't use Linuxmce until I buy a new monitor. Until then, I'm going to use mythtv by itself as my media center. So, does anyone know how to get all the buttons working in mythtv. I know that the arrows work, but the channel change buttons aren't even registering in the set keys area. Neither do the play, pause, etc buttons, nor volume. Now, I don't think this should be too hard because becuase system>preferences>keyboard shortcuts recognizes the play buttons. It doesn't however register the volume/channel. So does anyone know how to configure the fiire chief? Or is there a way to map the button presses to some key that mythtv recognizes?

P.S. once I get a monitor (the resolution was just way too low for Linuxmce (640x480)), I'll probably try linux mce again.
