no, it is necessary that you said. Because we tested on BD engraved (not original comics like you did). The patch Cinavia is not removed if it puts a message after 3 minutes of film. The principle of patch Cinavia is able to play AVI / MKV etc... or blu-ray disc engraved (anti copy protection skipped).
But the bdp_plugin.sprx file has never been supported on any existing CFW! This explains to you that the patch cinanvia is only a partial patch to read engraved video or video encoded AVI / MV or other format and not Blu-Ray or DVD originals that have DRM in them cinavia since the bdp_plugin.sprx is not patched.
In this case, it means that aunun patch Cinavia is therefore not functional if you share your principles.
Cinavia Remover Tools RC1 by ARCH for PS3 CFW (CEX) 4.3X / 4.XX
Following up on their previous release, today French PlayStation 3 developers Dev-Team-SPT / ARCH via arachetous have released Cinavia Remover Tools RC1 for all PS3 CFW (CEX) 4.3X / 4.XX Custom Firmware.
To quote, roughly translated: Here is a homebrew that will allow you to remove DRM protection Cinavia as simply as possible and it will also allow you to restore the Cinavia DRM protection if you want.
So, no need to include this function in a CFW with this homebrew to do it for you quickly.
Removes DRM Cinavia protection and restoration allows it if you wish.
