[MPlayer-users] multitrack vs multichanel

[jhd cero cero cero veintitres]

Hi all!

I'm trying play a movie in mplayer  with and stereo ambient sound track (in
two audio outputs) and 1 voice track in English (in one separate audio
output) and another voice track in Spanish (in other separate audio output).
This option is to try to play a movie translated in the two languages and
listen it with headphones. I want to use Jackd to link the differents audio
tracks with the differents outputs.

Anyone did any thing like that before?

Is possible to do anything like that with mplayer?

Thanks a lot!

                         Joaquín
