Hey,
There it is :

Big file because I did not compress anything (well I did convert the dts-hd tracks to FLAC for easier playback on PC but that's it) and it's a 6m40s extract (picture removed though) from the film (it's actually the very beginning, pay close attention to the music at the end in particular). Even played back on a stereo setup with downmixing the quality issue is still very noticeable and shocking to me so you can just listen to those with foobar2000/vlc/mpc-hc or whatever free software you fancy and a pair of headphones or decent speakers.
This archive contains :
-the original 5.1 mix from the old UK blu-ray (lossless)
-the 5.1 lossless English track from the new French blu-ray
-the lossy French DTS track from the new French blu-ray
-the lossy English AC3 mono track from the new French blu-ray
I won't say happy listening, because it's actually really bad

I'm not sure how to go about this but I want to try and contact them about it.
BTW Destroyer doesn't sound very good either, suffers from clipping too, are the other releases free from this? A sample of music from the credits would be enough to check that.
