Have you seen the 1080i HDTV version of EFNY that's floating around? If so, does it contain the original 2.0 mix?
From what I've read, the picture is way too dark on the US blu ray and is an SD upscale on the Euro/Australian blu rays. Aye, yaye, yaye...
If all this is true, then the HDTV version might be the way to go.
EDIT: So it looks like the HDTV version had 5.1 audio:

Probably the remix then, huh?
Anyway, more on the blu ray video side of things:
The HDTV video was definitely superior to both BD releases (had the DVD's colour/contrast and in high def) but, being 1080i MPEG2, probably had its own problems, I'm sure.
It would be nice to mux the 2.0 audio and the HDTV picture together, me thinks.
