I think you missed the point somewhere. The problem is IP cannot change the default CD/DVD icon - there are other programs which will. Of course the icon changes when you put a DVD in, its supposed to! As I said before, I don't have any difficulty changing the default drive icon, despite people saying it can't be done. All you need is the right program to do it - IP isn't it!
Someday the boffins at Stardock will figure out how to get IP to do it. Until then I will continue to use my alternative prog (which is four years old and originally designed for Win98 and yes, it does run ok on XP) which has no difficulty changing any type of icon.
