I am having issues playing the MKV video files I download on my friends TV, the TV shows I download have been playing just fine with no issues. The video portion of the files play flawlessly however the audio is another story. I believe the issue is because the movie files have 5.1 DTS audio, while the TV shows have AC3 stereo audio.
Could someone recommend a program, preferably freeware, that can down mix and convert the audio from 5.1 DTS to AC3 stereo?
