Explanation

The audio track of the video that you are copying contains a Cinavia code indicating that it is an unauthorized copy of professionally produced content.

Recommendation

If the video that you are copying is a professionally produced video (such as a movie or television show), you should obtain a copy that was made with the permission of the copyright owner.

If the video that you are copying is a home movie or other personal recording that includes some professionally produced material (including the audio track of a professionally produced movie or television show), in order to make a copy without interruption you will need to either copy only those parts of the recording that do not include professionally produced content or else you may create or obtain a version of the video that does not include this protected material.

For information on how this professionally produced material can be included in your home movies or other personal recordings in a way that will not be limited by Blu-ray Disc players, see Guidelines for Use of Content in Home Movies.
