Frankly, I'd prefer to work with a book or in a classroom setting. I can read faster than a person can speak in a video. OK, that contradicts my preference for the classroom, but in a class context, I can also directly interact with the instructor and the students. I can't exactly do that using a video. I know I keep telling everyone that I'm a visual learner, so you'd think that a DVD would be just about perfect, but I've always found them something of a problem. This isn't to say that video learning is bad in general or that this product is bad in particular. I'm just expressing my personal opinion before I move on.
