    I am trying to watch a .mkv file and get the below error. I can view the picture but there is no sound...

    "This file contains an audio track in an unknown format. You may need to install a DirectShow decoder in order to hear the soundtrack of this file"

    I have searched google for "directshow audio decoder for mac" and just don't seem to be getting anywhere. Can someone please give me a link to the download.

    Are you using Quicktime? Try Perian, it adds support for many formats

    I found that with QuickTime and perian installed I still couldn't play some file formats, I downloaded vlc and I have never found a file that it cannot play, all be it the interface is not as nice.

    Try it and see if it will play the files?

    Just for the record, there are no DirectShow codecs for OSX because DirectShow is a Windows technology, part of DirectX.

    Perian has allowed me to play all files. I don't like VLC because its user interface kinda sucks and I find that on some videos the picture quality is also worse than when using Movist (which also supports FFMPEG as well as Perian) or Quicktime with Perian.
