Symptom
If you burn a DVD from the Finder while the Classic environment is running, an alert box with this message may appear:
"Sorry, the operation could not be completed because an unexpected error occurred (Error code -1000)."
The blank DVD-R disc has not been affected and is still usable.
Solution
As a workaround, stop the Classic environment before attempting to burn a DVD-R. Follow these steps:
1. Choose System Preferences from the Apple menu.
2. Choose Classic from the View menu.
3. Click the Start/Stop tab, if necessary.
4. Click Stop.
