The people who have criticised this Blu-Ray disc fail to consider the following:This concert was filmed in 1983 on 16mm film at a time when even the best consumer video format(Laserdisc) had resolution less than what DVD has today. We can all agree that the performances  and surround sound mix on this Blu-Ray disc are superb. I've purchased both the Blu-Ray & DVD editions from Amazon's British website and viewed both on my 54" plasma T.V. and can assure you that the Blu-Ray disc's picture is dramatically superior to the DVD edition, even if Blu-Ray makes the film grain more visible(the concert was filmed under low-light conditions).
