Do you want to watch it fullscreen? I mean - 4:3 version switching from letterboxed 2.35:1 to 4:3 and back again? Such version would be rather useless for widescreen TVs users, cause non-anamorphic image looks like crap. Or maybe you want anamorphic with black bars from top & bottom disappearing and appearing on both sides?
If not, If you want it exactly the way TF:ROTF is, then it is identical to Blu-Ray release just in standard definition, so why anyone should bother to editing it? There's no difference if you have such an edit or BRrip.
What about people who aren't outfitted for BR but want to see the rest of the visual information?
1. Buy The Dark Knight on BR disc
2. download mkv BRrip and convert it to DVD to watch it on DVD player.
Buy BR player in the future.
