DVD Playback software that can play multiple audio tracks at once?

Odd question, I know, but does anyone know of any DVD player software
that can play, say, the english and spanish audio tracks at the same
time? For instance, send the English stereo track to the front two
channels and the spanish to the rear two?

Or separate tracks to separate audio devices even?

I'm running a MobMov:

and it seems it would be cool to have an English channel and a Spanish
channel.
