The Apple DVD Player application displays an alert box with an error message about the disc being dirty or scratched. This document applies to Mac OS 9.2 or earlier.
Symptom
The Apple DVD Player application displays an alert box with the following error message:
"Apple DVD Player has stopped because it's having problems playing the disc. The disc may be dirty or scratched, or the disc manufacturer may have encoded the disc incorrectly."
Solution
Upgrade to the latest version of the Apple DVD Player for your computer.
If you have a Macintosh with hardware-based DVD decoding, use Apple DVD Player 1.3, which is part of Mac OS 9. If your Macintosh has software decoding (if it came with Apple DVD Player 2.0 or later), check Apple Software Updates for the latest available version of Apple DVD Player.
If you have not upgraded to Mac OS 9, try these steps:
1. Eject the DVD-Video disc.
2. Press the Command, Option, and I keys while inserting the DVD-Video disc. This causes the computer to read the disc as an ISO 9660 formatted disc, rather than a UDF formatted disc. If the disc appears on the desktop, but has the DVD emblem on its icon, then it has not been accessed in the correct format. To access it correctly, control-click the icon and select "Mount as ISO 9660" from the contextual menu. The disc will become available with a generic icon.
3. Quit the Apple DVD Player application if necessary.
4. Open the Apple DVD Player application.
5. Play the movie. It should play, but you may still see the error message if the DVD-Video disc doesn't have an ISO 9660 volume.
