MakeMKV is your one-click solution to convert video that you own
into free and patents-unencumbered format that can be played
everywhere. MakeMKV is a format converter, otherwise called
transcoder. It converts the video clips from proprietary (and
usually encrypted) disc into a set of MKV files, preserving most
information but not changing it in any way. The MKV format can
store multiple video/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.
