Without seeing the vid, I can say this anyway: It's a hard balance for a student to get exactly what he wants. By mind control alone, I can't make the video slow down where I want it to, nor skip the stuff I already know. However, there are controls on the viewer that assist me. (I can loop, skip, etc.) I am sure if you post in Douglas' forum he will do everything he can to clarify the lesson.
...so ever since then, I always hang on to the buckle.
