Can't stop disk utility autostarting...

[eric44]

I put a blank DVD into my iMac and clicked the box which auto starts disk utility whenever a blank DVD is inserted.
I would like to switch this off but don't know how.
Also the DVD icon has disappeared from the desk top.
Please can anyone tell me how to put these things back as they were.
Many thanks.
