You could use an audio editor like rezound, snd, audacity to make a 2
stereo track wave file, play it with <some software handling jack and
multiple tracks> patch the english part to your speekers, and the
german part to the output where your head set is connected.
There are also tools that allow you to sync video to audio played by
jack (xjadeo could do the trick).
But all that is maybe a bit too much just to enjoy a movie ;-)
