The subtitles are prerendered PGS subtitles (playable in mpc-hc or mpv and probably vlc as well) because of the addition of third-party typesetting which I do not wish to reveal the source code to. For those who need text for translating to other languages, that can be found [here](http://baaro.buric.co/subtitles/dc276.ass). (This script is crippled and not intended for regular viewers.)
My preferred player for this file is mpv.
