I have a factory installed Sony CD-RW drive that stopped being able to burn CDs after I installed iTunes 8. In device manager, my CD and DVD drives have little warning signs on them, and come up with the error "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)" I have used a Registry Editing program (RegistryFix v. 7.0) as well as manually gone and removed the Upper and Lower Filters from the HKEY_LOCAL_MACHINESYSTEM section of the registry. I uninstalled and rebooted, and still nothing. Any ideas?
