 On January 2, 2007, the author posted the 1.0 version of the BackupHDDVD utility, which included support for the decoding of discs using volume keys. For several weeks following the utility's release no success using the author's key extraction technique was reported. In mid-January 2007, a volume key was published by another member of the Doom9 forum along with an explanation of the technique used to obtain it. Other forum members quickly discovered keys for different titles. Keys for many discs are now readily available on the internet.
