The MakeMKV application was developed to be 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.
MKV stands for "Matroska Video". Matroska is a container file format, capable of holding unlimited number of video, audio and subtitile tracks, along with any metadata. Practically this means that it is possible to put entire movie with multiple sound and subtitle tracks, chapters information and movie thumbnail into single file. Being open and patent-free Matroska gained broad support recently and quickly becomes de-facto standard for storing movies
