There is quite a bit of extraneous informational/promotional material at the start of the DVD. I was not interested in being told at length about the history and value of Tai Chi, I just wanted to learn how to do it.I gave this two stars because the instructors broke a basic rule for teaching any kind of physical movement: they started their teaching of each position while facing the camera, thereby forcing the viewer to try to learn by mirror image. They did break the positions down into steps and slowed them down, but as someone new to Tai Chi I still found it nearly impossible to follow along with a mirror image. Eventually the teachers turned around, but at that point they demonstrated the move at regular speed, assuming you had already mastered it. Which I hadn't. Not an insurmountable problem for the basic positions, but when they moved on to the advanced ones I gave up. And I'm not new to learning steps or positions, having had 20-plus years of dance lessons.
