for the main movie of LXG there are 5 audio files - 2 foreign, 3 english. one of the english ones is 6channel so i dont need that one but the other two are both 2channel. anyone have any idea which of the two i could get rid of because if i just put the movie on disk i dont want the director commentaries. i want to make sure i get the right sound file for the main movie. thanks in advance.
