mkv (dts audio support)

is there any way to see if the audio part of any mkv video is dts or ac3 ?
Answer #1
Mediainfo will list all the audio formats, subtitles, codecs in any file.

Answer #2
Convert all Mkv with mkv2vob and in settings it should say something similar to “convert dts to ac3” I have a media box and it won’t play dts
Answer #3
does 720 p mkv videos support dts?
or only the 1080 one
