The audio on the US BD is crap, they turned the bass way up so that it overwhelms all other sounds. I had to turn off my subwoofer to watch it.

The audio on the Dutch BD is regular DTS and Dolby Digital only, but it sounds serviceable. Not sure about the international theatrical cut in the JP BD set, I still need to watch it. But I assume the it's the same as the US BD since the JP set is also from Warner. At this point I'd probably just want to watch it with the Dolby Surround from the LD anyway.

There's some discussion of the Dutch BD here: http://www.avsforum.com/t/1234653/die-unendliche-geschichte-aka-the-neverending-story-comparison-pix
