My version has the documentary and I have one Blu-Ray disc. The whole idea of Blu-Ray is to fit more on a single disc... as well has being in HD of course.

My guess is that there's two versions of the DVD, on with just concert footage and a two-disc version with the doc on the second disc.

Having said that, I can't recall seeing a two-disc version advertised anywhere and only know about the standard and deluxe editions of "The Circle". The standard edition, you just get the album but with the deluxe edition, you get the album plus the doc. Is this where the confusion's coming in?
