| Try throwing out the DVD preference file (an old Mac trouble shooting tip) in /YourHardDrive/Users/YourUserName/Library/Preferences/ and throw out com.apple.DVDPlayer.plist .
Plus try to see if your Mac still sees the DVD drive by clicking on the top left Apple symbol, pull it down and select "About this Mac". When it pops up select 'More Info'. Then System Profiler (/Applications/Utilities/system Profiler) will launch. There highlight "Disk Burning" to see if your Mac still sees the drive.
Lastly have you cleaned out the DVD drive yet with compressed air and/or a CD/DVD dedicated laser cleaner disk yet?
