Disclaimer: my copy is region B and not purchased through Amazon, but rather through an Australian retail outlet.  That said, I am staggered at the asking price for this sub-par Blu-ray on this website and I must agree with the other two reviewers. The 5.1 mix is very disappointing, I think I got more out of it by using the ProLogic ll setting on my Pioneer receiver. I can't even access the "restored mono mix", the disk case actually says that it is NOT included, despite the included 2012 trailer stating that it IS on the disk. What a selling point - here's what your disk DOESN'T have on it!! On the doco Steve Howe says that the mix on the film was done brilliantly but this sounds like it was played back in an aircraft hangar and re-recorded by a bootlegger.  As for the video, the trailer shows the film to be in 16:9 but clearly that's not how it plays back. I suspect it is just cropped anyway so we probably aren't missing anything, but to the manufacturers, don't mislead people, please. I can't comment on accessible video resolution as I don't have a HD television. The film restoration wasn't too bad, I know that there wasn't much lighting to work with and this is probably as good as it gets.
