Brokeback Mountain UK vs. US audio

[Vashetti]

(I posted this in the UK section too, but I figured as it pertains to two version of the Blu-ray, I'd ask in here too, and this section receives a lot more attention as well)

Hey all, I've bought the UK release of Brokeback Mountain recently (not yet dispatched), and I've just noticed that the listing on here says the UK release only has Dolby Digital 5.1 audio, whilst the US release has DTS-HD Master Audio 5.1 (48kHz, 24-bit).

Is this correct? If so I'll cancel my order and import from somewhere (any suggestions, anyone?).

My partner loves this film and I want to make sure to get everything in the best quality.

Edit: according to this thread the UK version also has a noticeable pause when the layer changes, is this not in the US version?
