I defer to the experts, but from a quick glance, it looks like you are turning way too far on your backswing - the club is almost perpendicular to the ground at the top of your swing. I would have to guess that hurts your ball striking consistency since it would have to be a bit out of control with that much room to get back to the ball.
Also it looks like you may be set up 6 inches or so too far away from the ball, your weight looks to be a little too much on the toes.
The last thing I noticed in the DTL video is that you are certainly coming from over the top - try and focus on hitting the inside of the ball - I like to think "hit it out to the right" to get the feel I want.
This screencap is what I mean when I say you're turning too far on your backswing. If your chest is starting at 6 o'clock at address, you're rotating to about 1130. Impressive flexibility, but it has to kill consistency. I would shoot for rotating only to like 8 o'clock or 8:30.
