I have a couple of video files I'd like to play (containing obscure foreign kung-fu movies, heh). They are mkv files. One of them is in a folder that also contains a subtitle file, and it plays fine streaming to my PS3 with the Media Server. The subtitles show up fine (well, they look kind of crappy, but fine in general). The other one doesn't have any extra files attached, but when I play it on my PC, subtitles appear. However when I play it on my PS3, I see nothing. I looked at the subtitle options but nothing is jumping out at me, and after google searching, most people's problems seem to be with the additional subtitle files (though I could be wrong).
