Some PowerBook SuperDrives won't work with 8x DVD-R media
Products Affected
DVD Studio Pro 4.0, DVD Studio Pro, iDVD, PowerBook G4
Some earlier PowerBook G4 computers that have a SuperDrive with a 1x or a 2x DVD-R write speed may not be able to burn 8x DVD-R media reliably. Because of this, you should only use 2x or 4x DVD-R media.
Not sure what kind of SuperDrive you have in your PowerBook? Just do this:
- From the Apple menu, choose About This Mac.
- Click the More Info button to open Systen Profiler.
- In the resulting window, select Disc Burning (under Hardware).
Your SuperDrive model number will be listed in bold at the top of the pane. If you see UJ-815 or UJ-816 as part of the model, make sure that you only use 2x or 4x DVD-R media.

This could occur with the following PowerBook models if they have the UJ-815 or UJ-816 drive:
- PowerBook G4 (1GHz/867MHz)
- PowerBook G4 (17-inch)
- PowerBook G4 (12-inch)
- PowerBook G4 (15-inch FW800)
- PowerBook G4 (12-inch DVI)
- PowerBook G4 (17-inch 1.33GHz)
