Does wd tv live support mkv file with external subtitles(src file) in dlna mode?

Do you mean .srt?

Click on option, subtitle and select the subtitle from that option.

Thank you.

Yes, I mean .srt file.

But, there is no subtitle option, if mkv file is playing.

Names of .srt and .mkv must be the same.

i.e.:

Movie.mkv

Movie.srt
