MPlayer Occasional Subtitles. How?

[japher]

hi all,

does anyone know how to make mplayer play the occasional subtitles necessary for films like the godfather or kill bill?

 

if my dvd command is: mplayer -slang en dvd://

then this would give constant english subtitles, but what i need, is subtitles only when the foreign langiage is spoken. this works on a normal dvd player (of course), but it also works fine in xine. is it possible to get mplayer to do the same?

 

if the command is just: mplayer dvd://

then i get no subtitles at all even if, for instance, someone in the godfather is speaking italian, of someone in kill bill is speaking japanese.

 

anyone else have this working correctly?
