What are you using to rip/convert the DTS-HD MA tracks to LPCM? I've only recently began to rip surround tracks from my blu-rays (in the past I've just ripped any hi-res stereo) and have been able to rip using makemkv any LPCM streams but when I try DTS-HD MA tracks, when I demux the audio I'm only getting the lossy DTS core tracks instead.
I watched this the other night and really enjoyed it. Cannot fault the editing, camera work, audio or the content at all. The video quality I found to be adequate but could have been better with more careful encoding (I can't remember what the streams looked like when I ripped the disc but I have a feeling that there were/are 2 video streams - 1 with the interview segments included and 1 without). If so, it would have made sense to seamless branch those.
One thing I would have liked is some kind of intro or outro credits - I'm a sucker for those but it doesn't detract from a fantastic release of course.
Haven't listened to the alt mix yet but the main 'discete' mix is superb!
