Just a though but if you disable the service you might still get some error messages involved. You can completely disable XP's CD burning feature by also...

1) run gpedit.msc, User Configuration\Administrative Templates\Windows Explorer - Remove CD Burning features
2) run comexp.msc, Console Root\Computers\My Computer\DCOM Config , right click on Microsoft IMAPI, select properties\location, and uncheck 'Run application on this computer'.
