It relation to other CB DVDs that I have, the quality of this one is pretty good. Only minor quibbles with some of the content so far, and that's after a lot digging. This DVD is pretty extensive and contains a lot of chapters - also included (I wish they did this more) is a separate DB of important games, and another full of extra analysis not covered in the DVD.

Pretty good all around - Negi is a pretty great theoretician - you sort of get the impression that he's deeply studied this stuff for his own games and notes and that he's just releasing all of it now because he's mostly retiring from competitive chess.
