is the video bitrate of this BD 21939 kbps of the DC?
in case its this edition, from what Ive read the best PQ of the theatrical cut is still supposed to have the french studio HD DVD and for the DC the spanish Studio canal HD DVD(/BD?). the JPN BN has some edge enhancement compared to the Studio canal and is supposed to have a slightly worse AR stretch/crop.
not meant as complaint or anything, just as a hint that there might be even a tiny bit of room for improvement if you or anyone else feel like getting the very best result possible.
