There is no need for Event Ghost to use Boxee with this remote.
Just copy/paste this code into a file called Boxee.xml and save it in this path "C:\Documents and Settings\All Users\Application Data\SnapStream\Firefly\Profiles" on XP. It's a little different on Vista. I believe the path is "C:\ProgramData\SnapStream\Firefly\Profiles", not exactly sure. Then you can edit GLOBAL.xml to launch Boxee with the "Firefly" button. This is the code for the "Firefly" button.
<Actions Button="Firefly" Description="Boxee">
<LaunchAction ActivationState="Down" Program="C:\Program Files\Boxee\BOXEE.exe" Arguments="-fs -p" />
<PlaySoundAction ActivationState="Down" Sound="Select" />
</Actions>
Just make sure you don't have 2 entries for the "Firefly" button.
Here is the Boxee.xml code.
