I know that if you instal a aftermarket eg. nero, etc burning software, it becomes the default.
There is a easy way to restore XP'S default software, but sorry I forget. I read it in a comprehensive WinXP manual in a bookshop. Also, you can select which software is used.
Try Microsofts FAQ section at there web site and if all else fails, do a XP repair with the OS CD's.
