Has anyone tried the Sony Training DVDs
(1) Digital Video & Audio Production (http://www.sonycreativesoftware.com/products/product.asp?pid=496), and
(2) The Seminar Series (http://www.sonycreativesoftware.com/products/product.asp?pid=495)?

I see these are on sale, but I don't know whether it would be better to buy these or some dvds from VASST.

thanks
