Recently started having trouble playing downloaded movies through the DivX player. .mkv, .avi, it all has trouble. Video playback works, but upon opening the video file, it says "Error DTS Audio. Player does not recognize the audio in this video. Additional software is required to play." and is silent.

I'm using Windows 7 x64. I've downloaded the AC3 filter 2.6 already which is supposed to help. I've restarted the program, but so far has done nothing. I can watch the video, but there's still no sound. Should I try downloading a different filter? I'm so lost...
