Not really any changes to my knowledge. Apparently one shot is shortened because it was impossible to pan & scan properly. I still am not even sure about that though.
I’ve never understood why some folks have a soft spot for pan and scan. I mean, I grew up on them, even into the early DVD era, but now I can’t bear to watch them. Even 2.45:1 cropped to 16x9 for cable eeks me.
