you're right!! Either I missed it when I was scrolling thru the audio tracks, or forgot it was there and later read the back of the box which only shows English 2.0. I've corrected my post.
My UK Masterpiece Psycho has English 2.0 mono (DTS-HD MA 2.0) and English 5.1 (DTS-HD MA 5.1).
The original poster was referring to "Vertigo." I dont think there is a stand-alone blu of "Vertigo."
The UK stand-alone BD (region-free) contains the original mono track in a lossless format. I don't believe any other Blu-ray version does.
