Yes, it depends what technique you are trying to employ. The video is on the EC (ExtremeCarving) form, where as most people here use (what to call it? Standard/ Normal/ Bomber/ Angulation?). When I went a couple weeks ago and made that post, I was having a lot of difficulty because I was trying to employ different techniques that were contradicting each-other. When I went last week, I made much more progress just focusing on one. Sadly, I have been unable to find any good beginner instructional videos besides Corey's Intermediate and Steeps clinics on the "standard" technique.
Lessons are great if you have access to them (I do not). Otherwise make sure your gear and bindings are set up correctly, and focus on your sholders, hips, weighting, driving the knees, and moving directly across the board to initiate turns. Thats what I am doing atleast, so correct me if I am wrong :)
