I got some movies from a couple of guys I work with and they are MKV files. Windows media player doesn't support that so I was searching the web for players to use. I tried VLC media player but the movie was very choppy and would pixel a lot. I then tried DivX the video plays perfectly now, but there is no sound! The video is telling me I need Dolby ACS audio code 8192. I searched for the CODE downloaded and installed and that didn't work. DivX.com says AC3Filter, I downloaded and tried AC3Filter and that didn't work either. I was looking at AC3Filter and was wondering if I just need to configure it, for it to work properly. Any help would be appreciated. Video quality is perfect, but the sound is totally jacked, it might play for a second, the it freezes making the same sound over and over.
