When you try to play a DVD-RW or a DVD+RW disk by using either Windows Media Player or Sonic CinePlayer from Sonic Solutions, you may receive the following error message:
The DVD key exchange for copy protection has failed. Playback is not possible.
This issue occurs when Copy Protection for Recordable Media (CPRM) is enabled for the DVD-RW or the DVD+RW disk, but the disk is not encrypted. The DVD component that is used to play back the DVD-RW or the DVD+RW disk tries to start an encrypted session, and it is unsuccessful because the disk is not encrypted.
