Does anyone have a list of Dolby Digital soundtracks where it is beneficial to use EX encoding even though the track is not specifically labeled as EX? Some I can think of are Signs, Starship Troopers, Men in Black II, the Foreigner, and the Fifth Element. On another note, why do Superbit dvds only have 5.1 audio? I mean, why not give them the 5.1 EX and 6.1 ES treatment? I sure wish Columbia would release a Black Hawk Down Superbit with DTS ES 6.1 audio.
