What do you find the best books and videos/DVD's about pilates (or pilates and a combination of something else like bellydance or yoga, I've noticed people mentioning the Suhaila video)? In addition to classes, or as a tool to learn pilates at home...

I have three books on pilates and a dvd that came with one of the books.
I don't attend classes, because I already take bellydance and yoga classes and have to make choices... And pilates doesn't have my main focus, bellydance has. I've learned pilates through books, and video taping and observing myself, and think that works well enough for me. I'd like to share the books I've been using, and am curious what other people have been working with.

- Pilates Body in Motion, Alycea Ungaro.
This is the book I use the most, very good descriptions, many clear, big photos in color, it teaches you the whole mat series with a preparation, a beginner, intermediate and advanced program. It also has two additional programs: The Wall Series plus working with the magic circle.
I find this book excellent.

- The Pilates Body, Brooke Siler
Another great book. The book has small black and white pictures, which I find a pity. They are clear enough, but I like the above book better. It also has illustrations in it, to show you how you can visualize things. It has elaborate descriptions from a bit different viewpoint then Ungaro's, and therefore I think that this book is a wonderful addition to Ungaro's book.
It also teaches you the complete mat series (seperate beginner/intermediate/advanced programs), plus there's a program for your arms (training with weights) and an additional section with very advanced extra moves.

Both Alycea Ungaro and Brooke Siler are very renown trainers and studied directly under Romana Kryzanowska, one of Joseph Pilates' direct successors.

-Ground Control Pilates, Debbie Jenner, with DVD
I think this book perhaps only comes in Dutch. Jenner is American though, so I'm not quite sure, but she's based here in The Netherlands. I just bought this book in a bookstore before I received the other two through the internet (which to a bit), to get started already. I've seen the dvd once, but didn't really like it. Not that it isn't a useful one, but I don't like practicing with dvd's, since it's never in MY tempo, but the dvd surely shows you how certain moves are done in real time.
Also, the book doesn't teach you a certain program, there are different programs to choose from, with focus on specific areas of the body, for example: thighs and glutes, or back, or stomach. I don't think this is a really great book, I like the full mat program the other two books offer, because it is very complete. But this book has some very good pictures and descriptions in it, so although I hardly use it, I do see it as an addition to the above two. It has some excercises in it, which can't be found in the other two books, and which I found helpful. This is a book I refer to if I need just one or two excercises for specific reasons.

Overall, I think it's better to study more than one book on the subject to get a broader view of pilates.
