Vidio analysis software

[M4rtyn]

I have been using David leadbetter's interactive software for a while now, and have found it excellent I have lessons and give my sons lessons as well. trips to the range are productive and positive. Most importantly not practising a bad swing over and over again, and as all the lessons involve videoing their swing then showing them their mistakes and a corrective drill so they keep coming back (also they are cheapskates).

BTW, If anybody from my posts thinks I like gadgets and technology? Right on! might be because I used to be an engineer by trade.

Has anybody used same or similar software?
How was it?
