AnyDVD is a device driver for Microsoft Windows which allows decryption of DVDs on the fly, as well as targeted removal of copy preventions and user operation prohibitions (UOPs). With an upgrade, it will also do the same for HD DVD and Blu-ray Disc. The AnyDVD program runs in the background, making discs unrestricted and region-free. In addition to removing digital restrictions, AnyDVD will also defeat Macrovision analog copy prevention. Analog prevention distorts the video signal to prevent high quality copying from the output. AnyDVD is also able to remove copy-prevention from audio CDs. As of version 6.1.4.3, AnyDVD has a revised ripper that removes Sony ARccOS Protection, Macrovision RipGuard, and other structural preventions and repairs both intentional and unintentional mastering errors. It ensures strict compliance with third-party tools, particularly DVD Shrink and Nero Recode. The ripper module is based on code from Elby's CloneDVD. Old versions used a ripper based on FixVTS, but FixVTS was shut down by legal threats from Sony in June 2007. == Advanced technical characteristics == On February 17, 2007, SlySoft released ''AnyDVD HD''. AnyDVD and AnyDVD HD are in fact the same piece of software, but the license key determines whether the HD aspects of the software are available to the user. When the HD part of the software is enabled it permits access to HD DVDs and Blu-ray Discs, including decryption of AACS encrypted discs. In the case of Blu-ray Discs, it also supports region code removal (HD DVD has no region code). Besides dealing with DVD copying issues, AnyDVD can also work in the background to automatically detect and remove additional data sessions contained on Audio CDs which contain copy-prevention measures. This allows audio tracks to be directly accessed on the system for direct playback and for access by CD extraction software. Intentional tracking errors in the audio may also be discovered, for example, those errors involved with key2AudioXS, which may cause major skipping distortions in the ripped audio tracks. By bypassing these methods AnyDVD can provide clean, distortion-free playback and ripping. On March 19, 2008, SlySoft released version 6.4.0.0 of AnyDVD HD, which removes BD+ as well. Some Blu-ray Disc software players have removed the ability of movie playback from folders on a hard drive. AnyDVD HD has since version 6.4.6.2, August 22, 2008, included the ability to rip movies to an ISO format. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AnyDVD」の詳細全文を読む スポンサード リンク
