This is a great idea. Think every club should make sure its members see it - what about it on loop in Pro Shops for when visitors turn up to pay. Nothing worse than a pay and play course where noone knows the etiquette
It is a good idea but the only trouble is I should think that anybody who takes the time to view the video is likely to be someone who is respectful to others and displays good etiquette anyway. The people who most probably need to view the video would be less likely to watch it, apart from beginners who are keen to play the game the way it should be for which purpose the video is great. I think it's a brilliant idea getting Harrington to do it though- that should encourage people to follow the instructions given, and fair play to Padraig for agreeing to participate.
I would like to see it playing on a continual loop in the pro shop of a course or each junior member should be given a DVD of this when they join a club.
