I can tell you point blank: watching a video does ABSOLUTELY NOTHING for me. I could watch a video 500x it probably wouldnt make a lick of difference to my performance in the actual fight. That doesn't make me stupid, its just the difference between my learning style and someone else's. Not everyone learns the same. Some are hands-on, some are visual, some are verbal, some are able to easily extrapolate from text.
To each their own, what I'd like to see more of is learning parties being more welcoming and less abrasive. If you're all learning then accept that there will be failures, in some cases many! Be patient and at the end of the day we'll all be masters of the fight!
