At long last, the Windows 8 Metro environment has a decent media player that can play MKV files: VLC for Windows 8! VLC Media Player Beta for Windows 8 is a complete reimagining of VLC for Microsoft's touch-oriented Metro interface, but still with most of the functionality that makes the Desktop version of VLC so awesome. VLC for Windows 8 includes support for the MKV container format, the H.264 codec (along with its various containers/file formats), and almost every other codec under the sun (just like VLC on the Desktop).
