This isn't meant to disparage, but is it possible you just didn't get it?
I would hope a DVD could explain the system so everyone understood but it's vastly different than being taught by the instructor. With a live instructor you can ask questions to better understand the material. I don't know the ethics with it being a loaner copy, but if I had purchased the DVD and didn't get it or see the sizzle, I would have contacted Geno and asked him about it. You know, give him a chance to "make it right."
He's a great instructor and can explain something a dozen ways so it makes sense to the individual student.
I got a free lesson from Geno and it really helped with an issue I was having, where shooting to one side was stronger than the other. I bought the DVD (can't remember the price) and watched it after the Skype session. I re-watched it about a year later for a refresher. I think the DVD is just fine, but obviously you will get more out of it by talking with an instructor and letting him watch and coach you as you learn the system.
I don't get the hate. You didn't buy anything from him, but you act like he straight ripped you off. It's a bit unfair considering that if you were the original purchaser there is a chance he could have explained it over an email or a phone call.
I like and respect your opinion, but I don't think your attacks on Geno are easily justified. He didn't see one dime from you, nor did you give him a chance to explain what you weren't seeing.
