Streamworks Audio tutorials?

Just wondering if anyone has tried any of these? There are videos for Ozone 4, Melodyne, Dimension Pro, Rapture and they look pretty reasonable $ wise. There is some sample video on the site, but I was wondering if anyone has tried any and if they are just online descriptions of the interface and buttons rather than more details and tricks and tips. Any thoughts?
