This idea of preserving stage productions on video is an interesting one. The blurb on their site "We find the best of these shows, shoot multiple performances with multiple digital cameras using professional crew and equipment..." reminded me of the technique that was used to make the film of Richard Burton's Hamlet. I'd often wondered why that kind of thing hadn't been done more often, looks as if it is now, although I suppose it's been done, on-and-off, for a long time (remembering that newsreel record of some of Welles' "voodoo" Macbeth).
I wonder why the video has a different title from the play though? I suppose The Magnificent Welles makes the content and subject clearer to the casual observer, but Lost Eden is a better title, IMHO.
