You insert the digital copies to device for playback, but end up with muted audio or half-way stop. If you can't get rid of Cinavia protection or just bypass it, you rip Cinavia DVD or Blu ray disc with problematic copies.
Why it matters: when you make a personal digital copy of your Cinavia protected DVD or Blu ray movies, this DRM protection will hold you back.
The main user of this protection is Sony studios and distribution companies. Currently, most Hollywood studios are reluctant to adopt it due to its high costs. Have to mention this DRM tech is exceedingly expensive for a studio to use, requiring a great deal of investment in proprietary hardware and licensing, plus additional licensing fees per release and even per disc. And now almost all consumer Blu-ray Disc players from 2012 are demanded to support Cinavia watermarking detection (from wikipedia). If not, the audio will either be muted or playback will stop altogether. The second protection is for hardware - Blu ray player, which should have the ability to detect Cinavia protected movies and check whether the movies are authorized or not. The first protection is a watermark that is implanted into the audio channel of the movie. It's as part of AACS and digital rights management system with two-tier system.
