MakeMKV

MakeMKV is a format converter, otherwise called "transcoder". It converts the video clips from disc into a set of MKV files, preserving most information but not changing it in any way. The MKV format can store multiple video or audio tracks with all meta-information and preserve chapters. There are many players that can play MKV files nearly on all platforms, and there are tools to convert MKV files to many formats, including DVD and Blu-ray discs. Additionally MakeMKV can instantly stream decrypted video without intermediate conversion to wide range of players, so you may watch Blu-ray and DVD discs with your favorite player on your favorite OS or on your favorite device.
