AWESOME! I was just thinking, wouldn't 4.1 be more fitting and better represent the original mix? I don't really understand sound and if it would be practical but if I understand it correctly, there are four channels matrixed in the 93 mix, right? So those would translate into the four original channels and the bass channel would then be added. If I recall correctly this is the way the 4.2 mix was presented on the Alien BD.
Just a though, I don't really understand all of this properly.
