I already bought The Wall collector's edition and really liked it. The bluray's content is what I really wanted. It's actually the first time I saw the complete concert film. The North American edition was the best since it was the latest. The Wembley footage was rare. So bad they never made any full-length concert film after Live at Pompeii.
I don't have a good hi-fi system at home, so I never got to try the 5.1 mix on bluray.
