Adding choices to "Edit..Preferences..Media..Music Player"

[soze]

I'd like gtkpod to launch when plugging in my ipod. But under edit..preferences..media in Nautilus, under "Music Player" the only applications listed are Rythumbox and Banshee.

How can applications be added to this list?

I'd like to add Picasa to photo, AmaroK to music player. Please someone help us.
