The PlayStation 3 system cannot read the copyright protection of the Blu-ray Disc. Solution Make sure the disc is not dirty or scratched. If the disc is scratched and other discs work, you may need to replace the disc. Make sure you have updated to the latest PlayStation 3 system software so that your system has the latest list of copyright protection keys.
