Hi,
first of all: AppleŽ Remote != Front Row != Remote Buddy. If you can 
control Front Row, you don't automatically have an AppleŽ Remote 
Emulation. Usually just key presses are used for that. I assume this 
is also the case for the FR script of Clicker. And even with an 
AppleŽ Remote Emulation, you can't automatically control Remote Buddy 
with it (you can under some circumstances, but not per se).
So, I would be surprised if it would work. That said, I have never 
seen Clicker in action and thus also don't know what the FR script is 
doing.
What should work - in general, but with limitations - though, is if 
you can get Clicker to issue key presses for the HotKey Remote. You 
can configure the HotKeys Remote Buddy should listen and react to in 
Preferences > Hardware > HotKey Remote > Options.
The event would then be routed like this:
Clicker > Keypress > Remote Buddy's Hotkey Remote > mapped to button 
press > button press mapped to action > triggers action in Remote Buddy.
Hope that helps.
Best regards, 
Felix
