Multiple Open With windows when inserting media

I can’t seem to figure out why, when I insert any type of media (audio cd, dvd, usb, ipod), I get two or three Open With windows.

Any suggestions on where to start looking? Is there a script that is called whenever new media is mounted? Thanks in advance!

Cheers,
