The system deliberately creates corrupted sectors on the DVD, which leads DVD copying software to produce errors and most DVD players such as Sony DVPCX995, Toshiba SD4700, etc won't access to the areas (see how to successfully copy DVD with bad sector). Sony ARccOS DVD protection is a copy-restriction system used on most Sony DVDs. Thus, videos copied from DVDs encoded with APS become garbled and unwatchable. It functions by adding pulses and forcing copies to be degraded or inhibited when copies are made of video signals containing the Macrovision signals.

The Analog Protection System (APS)ĪPS is another DVD DRM system originally developed by Macrovision, intended to restrict copying or redistributing DVDs. Many DVD ripping programs fail to handle Disney DVDs with error messages like 'Failed to open disc', 'The volume key is unknown for disc', or they output short segments. Representative movies protected with Disney X-project measure include Black Panther, Coco, Zootopia, Moana, Beauty and the Beast, Pirates of the Caribbean: Dead Men Tell No Tales, Guardians of the Galaxy Vol.2, Star Wars 8, Cars 3, etc.

Some programs, though equipped with protected DVD decrypting feature and managing to rip the Disney copy protected DVD, but output videos in disorder or turn out to be out of step.

Worse still, the Disney new copy protection scheme may lead to crash halfway when ripping Disney protected DVDs with Handbrake, MakeMKV or other free DVD ripper software. And newer DVDs appear in an oversized way, up to 50GB, making it impossible to make a backup of it.
