I've had the Blu Ray for quite awhile and have been super happy with the overall picture and audio quality of the film. I also decided what the hell! I'll pick up the DVD copy to despite the high chances of the quality being lower.
I know that there are a lot of complaints about both versions, but in my opinion, I honestly don't mind either copy. I like watching the Blu Ray version. Hands down. Best way to see it. But, I picked up the 2-disc special edition only because I had a hunch that the IMax footage that was shown seperately would be shown in their original IMax format.
Lo, and behold! I had a screen comparison and I was spot on. The 2nd disc IMax footage definitely has the IMax aspect ratio as is intended to be shown. And despite the picture being superior on the Blu-Ray, it's still cropped from the IMax format. All in all, I'd say that I got the DVD for that reason alone.
On the downside of it when I think about it, I wish that they'd have included the IMax footage seperately on the Blu Ray as well in it's entire picture format too. Also, despite it showing all the IMax sequences seperately, I would have thought they'd include ALL their scenes shot in IMax. But no, they left out most of the establishing aerial shots out of that feature.
BTW, I logged onto Blu Ray Live and they posted up three new featurettes. The first one focuses on James Newton Howard's score for Harvey Two Face. The second focuses on the Sound of the Batpod. It was covered in the Blu Ray featurette but the BD-Live version goes a little more in depth with the sounds that make up the Batpod. And lastly, the last featurette has a brief interview with Zimmer and Nolan regarding Zimmer's crazy idea to perform a track from Dark Knight live at the NYC premiere. Then shows the performance in its entirety.
It's cool and all, but I really hate logging on to BD-Live just to watch these features when they could have just put it on the 2nd disc. I like to just pop in the disc and watch it right off the bat. Not wait for my connection to log me on and then wait for the streaming video to buffer it. It got super annoying every time it had to stop to buffer the video. For those of you who run into the same problem, just pause the video before it starts and let it complete. I just walked out of the room for a while and then came back and played it. It's a hassle but, it's the only way to keep from getting annoyed with the constant pause in mid-sentence of the interviews.
