Okay, if you wanna resolve your problem you need to do the following:
1) A) Download the "Matroska Pack" from
www.matroska.org , it's the official support for *.mkv files. Be warned though, some of the Matroska pack's features, namely the VSfilter and the FFDshow, interfere with *.ogm files, you can choose not to install those features (in fact I recommend that you don't) but it may cause some problems along the way.
B) If an *.mkv file doesn't play right, just maneuver between installing and not installing these features.
2) A) You should also download the "Combined Comunity Codec Pack" (CCCP for short) from
http://www.free-codecs.com/download/Com ... c_Pack.htm , this pack will optimise your Matroska pack and provide it with all the necessary codecs you might need. You can also find the CCCP in the R.O.D OAV pack.
B) If you encounter problems, reffer to section 1B of this explanation.
