Commercial Blu-ray discs like movies and documentaries are encrypted with region code and copy protection. As a result, these discs can't be played or copied unless you remove these restrictions with the Blu-ray ripping software that can break them. For example, VideoByte BD-DVD Ripper can easily remove off all types of DRM protections of Blu-ray discs including APS, CSS, ARccOS, CPRM, AACS, BD+, and Cinavia. You may want to give it a shot.
