I wouldn't worry about Cinavia too much. Verance was the company who also designed the copy protection and watermarking technology used on DVD-Audio discs and look how that turned out. :)
In addition to that, the HDCP master key was leaked last year which would make it possible to intercept the protected audio and video streams as they leave the playback device.Quote:
DVD-Audio's copy protection was overcome in 2005 by tools which allow data to be decrypted or converted to 6 channel .WAV files without going through lossy digital-to-analog conversion. Previously that conversion had required expensive equipment to retain all 6 channels of audio rather than having it downmixed to stereo. In the digital method, the decryption is done by a commercial software player which has been patched to allow access to the unprotected audio.
In 2007 the encryption scheme was overcome with a tool called dvdcpxm. In 12 February 2008 a program called DVD-Audio Explorer was released, containing aforementioned libdvdcpxm coupled with an open source MLP decoder.
Like DVD-Video decryption, such tools may be illegal to use in the United States under the controversial Digital Millennium Copyright Act. While the Recording Industry Association of America has been successful in keeping these tools off websites, they are still distributed on P2P file sharing networks and newsgroups. Additionally, in 2007 the widely-used commercial software DVDFab Platinum added DVD-Audio decryption, allowing users to backup a full DVD-A image to ISO. (Source)
If links appearing on Twitter are to be believed (and right now thereís no reason to doubt them) then the master key for High-bandwidth Digital Content Protection (HDCP) has been revealed, making the DRM baked into devices such as Blu-ray players effectively dead.
This is a big deal. Very big deal. It means that while HDCP devices have their own set of keys that can be revoked when they enter the public domain, uncovering the master key means that new source or sink keys can be created and thereís nothing that can be done to block them short of changing the master key, and thatís not going to happen. Why? Because changing the master key would effectively kill all current players, set-top boxes and HDMI-enabled devices. While some devices have upgradable firmware, plenty donít, making a change of master key implausible. So, if this is the real deal, HDCP is dead. (Source)
