[SOLVED] removing stuff from the context/right click menu

[martin saint martin]

lovin´ the ubuntu 64-bit. i´ ve tried out several music players that ubuntu will support, and i now have one that i will keep for some time(audacious). the problem is that in the right click menu are the old media players that i was testing, most of which i will not be using. to keep thing simple and easy for friends using this computer, i would like to remove choices that will led to nowhere. i looking for someone who can tell me how to add/remove stuff from the context/right click menu.
