No Audio in .mkv file playing on divX Player

Hi all, I'm aware this is a widespread issue with 10.8> users and I've tried to troubleshoot it myself but I can't seem to fix it.

I'm trying to watch a .mkv file on divX player - but when opened, there is no audio and the following error message appears:

"Error Dolby AC3 Audio

Player does not recognize the audio in this video. Additional Software is required to play. It may be available from the DivX Support website."

This is the second file I've tried this week which has encountered the same problem.

I went on to the website and looked at the drivers, and it suggested Perian which I already have installed on my mac.

Are Perian and divX not working together properly in this instance? Or do I need to download something else?

I'm using a 2010 macbook Pro with OS X 10.9.2

Thanks for any help!

 

Works perfect. Thank you! DivX player is utterly useless!
