Create a new folder in your hard disk, make a BSplayer.ini file that specifies the subtitles folder of your movie and place my launcher and the BSplayer.ini into that folder. It's that simple!
However, there is no way to make BSplayer search into 2 or more different directories for the subtitles automatically.
