A few months back Sony updated
their new Terms of Service to include "automatic updates or upgrades which may change your current operating system, cause a loss of data or content or cause a loss of functionalities or utilities" and with the recent PS3 Firmware 3.41
it appears Sony has added in http://www.cinavia.com/languages/english/index.html as an automatic PS3 download.
For those unaware, Cinavia DRM technology is an audio watermarking technology that takes aim at pirates, and those trying to playback movie downloads via their PlayStation 3 consoles, and is part of the content protection system included in Blu-ray Disc players.
According to the official site, the watermarking works by "comparing the source of the audio to the format in which a movie was released (ie theatrical or commercial disc), and if the watermarked audio source detects a difference, the movie will either be mute (but most likely not play at all)."
To quote on a temporary 'fix' from alexsaeed8
Recently PS3 has come out with this new update that automatically downloads and installs this program called "Cinavia" which protects against piracy movies by analyzing the sound of the movie that is playing and compares that to the original version to see if it matches and based on that it will allow or doesn't allow the PS3 or BRDvd players to play the movie.
You will get 2 most common messages:
1: It will say it can't play the movie because of a copyright violation.
2: It will say the audio for this movie has been mute and it won't play any more sound, just the picture, it all depends.
So based on this information I have made a short video of how I have been watching movies on my ps3 and by passing the cinavia technology.
The only way I been able to watch movies is to speed it up by x1.5 or higher Cinavia can't pick up the sound at that speed, and it's not so bad once you get use to it.. at least for now until someone come out with another solution."
