Hi Pal
There is an excellent product on the market called LEADBETTER INTERACTIVE, this is a 5 dvd box set which covers all aspects of the golfswing from fundamentals to shot shaping, but best of all there is V1 swing analysis software which allows you to video your swing and upload it to one of david leadbetter's coaches who will then analyse your swing and give you the best drills to improve any swing faults.
I would reccommend this product to anybody who is serious about improving his/her game.

Good luck
