I have a movie which is in a .mkv file. The specs show the audio stream signal is entitled: "Danish DTS 5.1 Channel 1510 kbps". I took this movie on a USB drive and plugged it directly into my HD TV which has a USB port and the facility to play many different video/audio formats. The video is perfect. But the TV reports that the "Audio is in an unsupported format". And in fact there is no audio nor is there subtitles. The movie plays vid and audio on my computer with VLC which does play the subs. Do I have a chance at just converting only the audio to some other compatible format like "AC3"? How would I do that?
