A company I used to work for does DVD video tutorials. I actually did the tutorial for photoshop elements 5 and the new CS3. They are more for someone just starting out in photoshop but the company has tutorials for most of the photoshop software versions. Visit http://www.stacygajus.com/Pages/PhotoshopCS3.html This is the tutorial for CS3 and I am the voice on the demo. Again these are tutorials are more for someone just starting out with PS.
Good luck.
