What’s MKV video format?

An MKV file is a Matroska file, the Matroska Multimedia Container is an open standard free Container format . It is similar in conception to other containers like AVI, MP4 or ASF, but is entirely open in specification, with implementations consisting mostly of open source software. Matroska file types are .MKV for video (with subtitles and audio), .MKA for audio-only files and .MKS for subtitles only.

How to use Windows Media Player to play MKV video files?

Many people who download a file with the extension MKV will often try to play it back with video player software they have installed on their systems. Most of the time this doesn't work.
As it is based on DirectShow Windows Media Player will play back MKV files perfectly if you have the proper codecs and filters installed. A great help here is the Matroska Pack. This pack is an ideal solution for new users as it installs pretty much all you will need to play MKV files.
