The Matroska Media container is a very popular, open standard Multimedia container which is usually found as .MKV files. It is a very popular format in enthusiast circles and can be played directly in Windows Media Player with suitable codecs installed. We use the Combined Community Codec Pack (CCCP).
We ripped our BluRay disc of Sniper Reloaded to 1080P MKV and use Windows Media Player to playback the file.
1080p MKV contained files are demanding of the partnering hardware. The system requires 46 of the AMD A10 4600M time, although there are still enough cycles free for other tasks if needed.
