I installed the DivX codec pack. Windows Media Player now shows the video, but no sound.
When I try playing an MKV in DivX Plus Player, I get an error message:
"You may need an additional audio decoder to play the soundtrack of this file.
This file contains a track in the Dolby AC3 Audio (code "8192") format. You may need to install a DirectShow decoder for this audio format in order to hear the soundtrack of this file."
I downloaded a filter from www.divXmovies.com/faq, and it seems to work now.
Thanks,
Shane.
