This irritates me too - they obviously have the right idea, but they haven't implemented it at all well (similarly, I have a huge external USB disk with all sorts of (legit) media files on it - when I plug it in, Windows tries to search the entire disk to see what sort of action to recommend). The procedure described here (http://www.windowsnetworking.com/kbase/WindowsTips/WindowsXP/UserTips/Customization/DisableCDautoplayinWindowsXPPro.html) will stop autorun completely, but you need to have admin rights on the PC.
