Reverse Engineering and Emulation of BD+ Implementations
On November 8, 2007, SlySoft announced that BD+ discs can be copied with their AnyDVD HD software. This was possible because first generation BD+ titles did not check if AACS was present. This allowed a user to copy a BD to the harddrive and play it back from there using only a specific version of Cyberlink's PowerDVD (3319a), but not to transcode, otherwise manipulate the content or play it back from a burned BD-R or BD-RE. Updated versions of BD+ security code plugged this hole.
On January 9, 2008, engadgethd.com reported that Fox has stated that BD+ has yet to be compromised. When asked how hi-def 20th Century Fox titles had become available online, the rep reported that the titles were available as HD DVDs in Europe.
On March 3, 2008, SlySoft updated AnyDVD HD allowing the full decryption of BD+, allowing for not only the viewing of the film itself but also playing and copying disks with third-party software.
On March 19, 2008, a new version of AnyDVD HD was released (6.4.0.0) that supports the full removing of the BD+ copy protection for all titles released to date.
In May 2008 the Blu-ray release of Jumper introduced a modified version of BD+ security code which prevented the Slysoft AnyDVD HD software from removing BD+. This modified version was again circumvented by Slysoft several months after Jumper was initially released.
In August 2008, members of the Doom9 forum began work on an independent project to create an open-source implementation of BD+.
In late October 2008, the same Doom9 members made the first working repaired BD+ movie with the previously developed open source tools, and as of November 1, 2008, have created code to debug content produced for BD+'s virtual machine.
On November 2, 2008, Doom9 forums announced that early (pre-May 2008) BD+ discs can be played back using open source software only.
In early November 2008 multiple versions of BD+ security code were released which, according to Slysoft, may take a few months to circumvent.
On December 29, 2008 Slysoft announced that AnyDVD HD 6.5.0.2 decrypts copy protection on all current Blu-ray movies.
On February 13, 2009 a 4th version of BD+ security code was discovered on the movie Australia, rendering Slysoft's existing AnyDVD HD software ineffective.
On March 19, 2009 Slysoft announced that AnyDVD HD 6.5.3.1 adds support for some new BD+ protection in movies, e.g. Australia, The Robe, South Pacific. Some BD+ movies were not supported by Slysoft's update, e.g. Slumdog Millionaire, The Day the Earth Stood Still, Marley & Me, X-Men Trilogy. Since then, Slysoft has released several updates adding support for newer titles.
On October 7, 2009 support for BD+ was announced for MakeMKV, making it the second application capable of handling all BD+ discs released to date.
In 2010 three other companies released software that can decrypt BD+; DVD Fab. Blu-ray Copy, Pavtube Blu-ray Copy, and BlindWrite.

Famous quotes containing the words reverse, engineering and/or emulation:
“They shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more.”
—Bible: Hebrew Isaiah, 2:4.
The words reappear in Micah 4:3, and the reverse injunction is made in Joel 3:10 (”Beat your plowshares into swords ...”)
“Mining today is an affair of mathematics, of finance, of the latest in engineering skill. Cautious men behind polished desks in San Francisco figure out in advance the amount of metal to a cubic yard, the number of yards washed a day, the cost of each operation. They have no need of grubstakes.”
—Merle Colby, U.S. public relief program (1935-1943)
“Our children will not survive our habits of thinking, our failures of the spirit, our wreck of the universe into which we bring new life as blithely as we do. Mostly, our children will resemble our own misery and spite and anger, because we give them no choice about it. In the name of motherhood and fatherhood and education and good manners, we threaten and suffocate and bind and ensnare and bribe and trick children into wholesale emulation of our ways.”
—June Jordan (b. 1939)
