Query: not perfect, but it's only a couple hours

I agree that this DVD does gloss over a lot, and is hardly authoritative, but, it's a DVD not 14-week college course. Given the time restraints, I think this DVD does provide a great deal of useful insight. I think his technique of using live models of different body types really helps the viewer retain the key points he's making. I think some of the areas are more complicated that he's got time to address -- in particular hip rotation -- but no one would watch, let alone buy, a 12-hour dvd set. As it is, it's the best 2-hour introduction (or is it 3?) to anatomy for yoga that i've come across. Of course any yoga teacher interested in this approach should also have the Anatomy of Hatha Yoga, a book which will take you way, way more than 2 hours to read.
