Haven't used any DVD course for my own tickets but wanted to include something in my PPL syllabus so checked out (as in watched a random lesson for 30 mins) King's and Jepps DVD video courses.
I did not like Kings for two reasons. It was somewhat naive and too much emphasis was made on passing the written test instead of understanding the material. I may give it a try if I get some bimbo that can't memorize the question bank an attractive blonde student who finds multiple choice exams unreasonably challenging.
Jepps material was better, albeit somewhat dry. It follows the textbook structure but essentially is the same material with footage of airplanes.
Also heard good things about Sporty's but never had a chance to try, I wonder if they'd give out free evaluation copies for CFIs or FBOs (obviously I'm not ready to fork out 200 bucks just to check it out)
