Need a MKV codec?
I recommend using VLC media player (it can play MKV’s). Best part is it’s free, open source and completely free of spyware. It is also the near popular player out there.VLC media player is a highly portable multimedia player for various audio and video formats (MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, …) as well as DVDs, VCDs, and various streaming protocols. You can also try the Windows Media Player) which is able to play most video files out there.
Note that the MKV extension was made for high definition video file formats. You will also find this file being used in such players as the DivX 10 range of players. The format was developed in an open source scheme for TV shows under the Matroska brand. These Matroska format files comes in the following extensions : .mkv .mk3d .mka .mks.
Note that the MKV is only one extension and you will note why it was made for movies – subtitles. The following is how it is normally shown and its uses : .MKV for video (with subtitles and audio), .MK3D for stereoscopic video, .MKA for audio-only files, and .MKS for subtitles only. That’s the history of the extension in a nutshell. Since then Matroska has been incorporated into most players. See the Matroska Splitter on this website.
