The program is meant to be really simple in appearance and functionality. MKV Player consists of a single window with playback buttons and a timeline to move along the video. The buttons are non-standard; they feature words instead of the typical symbols – meaning you see "Play" instead of the traditional right-pointing arrow.
The settings in MKV Player are scarce and difficult to use. They’re hidden in a drop-down menu below the video screen, and only let you tweak video speed, subtitle delay, and file association. There are no equalizer or video effects, like you find in VLC Media Player. The program is not documented either.
If playing audio and video files is all you need to do, then MKV Player will be enough. If you’re looking for a more sophisticated piece of software, with more options and tools, you probably need to look somewhere else.
MKV Player is a very simple MKV video player with support only for the most basic functions. On the developer website of VSeven Software there isn't much information either. Converting MKV files to MP4 in order to play these files elsewhere is an option, and a program like Free MKV to MP4 Video Converter may help.
