I don't think it's very hard for the BSplayer developer team to fix this, but they are probably busy with other things right now so in the mean time you could try to use this little patch I wrote :

When you put it in your BSplayer plugin directory it will automaticly start to play files with the second audio stream (when it's present).
WARNING : it will not check what audio stream was playing before or check the language, it will ALWAYS play the second stream.
Enjoy,
