when all settings and agents are correctly set, PMS will download subtitles when available.
this is an excellent feature, which takes a lot of work out of your hands.
however, sometimes the subs are include/built-in inside the media-container, e.g. mkv
and PMS does not always see that.
this results in unnecessary addition of subs.
so, how can you easily disable these subs and easily enable them at a later date ??
