While browsing the British Dressage magazines I came across adverts about lessons on videos that you can watch on your desktop. I thought it was a very interesting idea and had a look at the websites:
www.dressageclinic.com and www.showjumperclinic.com.
There is a choice of European and North American trainers and the variety is enormous including Hubertus Schmidt, Rudolf Zeilinger, Alois Pollmann Schweckhorst, Jeroen Dubbeldam and many others.
There are also a few free videos that you can watch in both dressage and show jumping and I found them interesting but due to them being shown in a tiny resolution you really have to strain to see something. The commentary is live by trainers/riders/lecturers and it seems a nice, educational tool. The quality of the sound of the free videos is bad at times.
The membership gives you an access to about 40 training videos a month and they span work from Novice to Grand Prix. I haven't bought it but if anyone of you have and can say more please let me know!
