A very nice feature of this keyboard is that you can program your TV or amplifier's volume buttons while retaining the ability to use the default behaviour by holding Shift when you hit the volume keys.
Smirnoff, do you know if the additional buttons are going to be supported in MP 2.0? Onmine, most of the buttons at the top don't do anything; My Pictures, My Music, etc.
The majoriy of the shortcut buttons should work out of the box, however I did have to add support for My Radio and My TV (Live TV works okay) and possibly one other button that I can't remember right now.
The changes should be present in the recent CVS builds for the past two weeks or so and will also be in 0.2 when it is released.
If the problem persists create a support thread and we'll see whats going wrong for you.
