You might be thinking about a series of sports training videos produced by Sybervision. Currently they only have one on golf http://www.sybervision.com/Golf/golfmain.htm but their site says they are planning on brining the rest back into production.

There was another company that produced videos designed to program martial arts skills into the viewer. I don't know if the company has a web site or how many videos they produced but I do know they have 2 Ninjutsu videos (Ninja Night Warriors by Stephen Hayes http://www.skhquest.com/proshop/category.aspx?category=3 ) and at least 1 Wing Chung video.
