DLNA subtitle support?

Hi i am having trouble getting subtitles to display on the video when playing through DLNA. They are working on some of the files, but i can’t figure why or how to get it on everyone. It works on a couple of my video file thats stored in the folder videos >> movieFolder >> movie, srt file. This is where i have the video and srt file stored in the folder. Same thing with the other one video that works. I have another video stored in video >> moreVideos >> MyMovie >> movie, srt file . I can’t get it to work? How do i get it to work? The subtitles work file playing through Kodi, but not through DLNA, except the two i said work so far.
