Issue with The Dark Knight Blu-ray disc: Changing Aspect Ratios + Sound

[MikeZ.]

Funny...at 51 years old, I've gone from NO home video to full screen VHS to full screen DVDs to widescreen DVDs ( which became my passion to the point of ordering some films from Amazon UK because only full was available here in the US ) to Blu Ray which, depending on the aspect ratio, may sometimes appear as full screen...to the Dark Knight, that, when the aspect ratio changes, surprisingly DOESN'T bother me. Maybe after you've " seen it all," you're a little more open and flexible.
My " preferred " ? 2:40 Blu Ray w/DTS HD Master audio.
