Again news on DVD-Ranger today as the company has posted, what it calls, "A clarification to the CinEx HD misconceptions and disparagements". The developers have received lots of criticism since their release of CinEx and CinEx HD, modules to the DVD-Ranger software designed to remove the Blu-ray copy-protection Cinavia from movies.
While the sound quality of movies processed with the original CinEx module was far from perfect, with CinEx HD the company introduced a method for removing Cinavia from movies while maintaining good audio quality.
To achieve this, it requires the download of fairly large (100MB) database files. These could be freely downloaded from the DVD-Ranger website, (now only for registered members, and the downloads are also available as Torrent links) which made some people to experiment with them.
The databases contain some kind of audio and Myce users have questioned the way it work. Now DVD-Ranger has posted a statement on their website that should provide a reply to the allegations.
Over the course of last few weeks, there have been many fallacious statements and theories written about CinEx HD and the databases we use. These theories were purported by people who are neither connected nor are proficient with our software but more importantly lack a comprehensive knowledge of the Watermark System Cinavia.
Facts
The audio these people obtained during their crazy experimentations was of poor quality. Several parts of the audio were missing.
Why?
The reason is that the database contains a “First Pass“ during Cinavia cleanup process. What this means is that information that is stored in the database was created with our Cinavialabs software. This information and virtual function are used by DVD-Ranger to restore and repair the Cinavia marked audio. Seeing the database dedicated to a special movie, DVD-Ranger will always use this information to restore the audio, so that you can finally have a shadow audio inside.
But is this a full audio track?
No it is not.
This is because it is beyond the realms of existing technology; more specifically there is no codec available which allows you to compress a full movie audio stream to 100 MB and then decompress it to high quality 512 Kbps AC 6 Channel audio.
The most crucial point you ought to understand is that Cinavia is not a simple marker in the audio stream. Cinavia is a complex watermark that alters the audio completly. Put simply, it is wholly different to the original audio in all cases. There are different methods employed, such as drone out, to hide it. Cinavia is embedded inside the whole audio, in all frequencies and bands, in all channels.
So this misconceived notion that you can mix a non-Cinavia track and a Cinavia track to remove Cinavia is absolutely ridiculous and will never work. The main reason for the theory’s failure is that different characterstics of Cinavia will always crop up and exist in the new track too, meaning it will always be detected.
So can it work, if it’s written by many users?
No, it’s impossible.
We requested all the people claiming otherwise to bring in evidence supporting their theories but none were capable of presenting it. However, all of them were quite competent in writing an excuse.
It’s really amazing, too improbable to be a coincidence, that hundrets of CinEx HD users were able to successfully copy a Cinavia free movie while the self proclaimed “experts“ who professed and purported these wild theories could not.
Could it be that all of this only stems from their lack of objectivity?
