I owned the VHS tape and watched it many times.  I agree that the original footage is of poor quality and should have been much better.  It does have a bootleg look to it which is surprising considering DA Pennabaker is the filmmaker.  Nevetheless, it's the only video footage we have of a Ziggy Stardust concert, so I'll take what I can get. Notwithstanding my objections to the video quality, the remastered DVD is a major improvement from the VHS version.  I am giving the remastered DVD 4 stars for the historical significance and improved picture quality of this monumental concert.  The remastered DVD also has improved sound quality.  I only wish the director had done a better job filming this concert.  How could he possibly not grasp history in the making?  Long live Ziggy Stardust and his superb backup band including the legendary Mick Ronson!!
