Got the DVD's a couple of days ago. To answer another question, yes you can get them without the Medicus training club, you just have to go through several screens after ordering the DVD's where they try to add on extra purchases like that.
There's 4 DVD's in the box: 1) The Stack & Tilt Swing 2) Stack & Tilt - In Depth 3) Analyzing Your Shot 4) The Short Game. All by Bennett and Plummer. Very basic production, two camera setup, a couple of split screens to show swings, that's about as fancy as they got.
I've only had time to watch the first disc. About 1 hr 15 minutes; first 30 was taking the swing into different parts (stance/setup, backswing, downswing, follow through), last 45 talked more about swing mechanics, ball flight, etc and the theory behind it. Honestly, even though I've been a golf coach/teacher in the past and a total swing junkie, the last 45 I had trouble staying focused on what they were saying. It's pretty dry, and not especially well scripted. That being said, the first part of the DVD was worthwhile, spotted a couple of things in there that I hadn't learned yet about S&T, and found some things to check in my swing.
We'll see what the other DVD's contain, I'm not too hopeful that they'll have any higher production values, but content is more important than production. Overall, I'd say so far they were worth the price, especially since no pro out my way can teach S&T, otherwise a few lessons would have been a better bargain.
