can some one please explain why dts list their ES as 6.1 when dolby say 5.1? surely if it was 6.1,it would mean discrete? On the r3 dark water dvd it says 6.1es when its only 5.1 with a matrixed surround just like the dolby 5.1ex. Just find this to be very misleading,why dont dolby call theres 6.1ex? they are both using the same methods!!
