usually when u need to change subs, you also need to change cds or file.
in case u have 1 file and 2 srt files for the 1 video. i guess you will need to stick those 2 srt into 1 with some subtitles tools before u can play the movie.
uhm, i dont really think would be hard to put that in the next xbmc version right ?
if so, how would you put 2 srt subtitles into 1 file ?? have you done that before ?
