Late Phases (2014) US MPI Blu-ray:
1. It is region ALL, as checked by me, even though the back of the case says it is region A.
2. There seems to be an issue with the 2.0 audio track. I only have a stereo system, and for some movies multi-channel (5.1, 7.1 etc.) tracks cause issues, presumably where there is a slight delay on some channels. The delay is too short to sound like an echo, instead either being extremely short, giving a 'flange' effect, or slightly longer, giving the sound an unpleasant metallic quality. However, on this release, the roles are reversed - on my system the 5.1 track sounds fine, but the 2.0 track seems to have this unpleasant metallic quality (most noticeable on short loud sounds such as a door slamming). Possibly the 2.0 track was generated as a downmix from the 5.1 track with some of the tracks being slightly out of sync, but that is just a guess.
