    What is MKV?
    The Matroska Multimedia Container is an open standard free Container format, a file format that can hold an unlimited number of video, audio, picture or subtitle tracks inside a single file.


    How to play MKV?
    Easiest, play with latest VLC Media Player or MPC-HC. If you want to use Windows Media Player or other directshow players like Media Player Classic install haali media splitter, ffdshow and ac3filter.


    MKV to AVI DivX/Xvid
    Use HandBrake. Or use Xvid4PSP, Super, AutoMKV, Total Video Converter, Winavi, AllToAVI.


    MKV to DVD
    Use ConvertXtoDVD. If you get problem converting to DVD directly you can try use HandBrake and then convert the AVI to DVD.


    MKV to Xbox 360 or Playstation 3
    Use GotSENT or for Playstation 3 use MKV2VOB. If those wont work reconvert using Handbrake.


    MKV to MP4
    Use GotSENT. If it wont work reconvert to MP4 using Handbrake or Xvid4PSP.


    MKV to Blu-Ray/AVCHD
    Use MultiAVCHD.


    Problems
    Slow playback
    If the MKV contain H264 or VC-1 HD video(identify the video codec in a MKV with MediaInfo) try Media Player Classic Home Cinema or latest ffdshow or Coreavc and play with Media Player Classic. If that wont help you might need a new computer or a new graphic card because High Defination H264 and VC-1 video requires a fast computer.

    The subtitles disappear when converting
    Extract the subtitles with mkvextractgui and add it manually when you convert to DVD( with for example ConvertXtoDVD) or to AVI DivX/XviD (with for example Handbrake or Xvid4psp).

    Audio sync issues when you convert
    It's probably because of VFR video and it's not easy to solve. Try latest Handbrake or Xvid4psp. If that wont work Give UP, it's not worth the trouble. If you want to play mkv on your TV then get a HTPC or media center with MKV support see http://www.mpcclub.com/ .


    Okey, no more mkv questions.
