I have three teachers, practiced for 31 years, and still do not understand half of what they are trying to show me. One of my masters, Leung Shum, purposely only puts certain forms on DVD moving a certain way so he can detect if someone learned from videos or learned the true art from him or one of his seniors. My young sidei, anything pursued well is pursued over time. Unlike most in the young generation today, those of us who have been in it for awhile realize that the longer one trains, the more one does not know! The dvds cannot show you what it is like to feel true jing from your teacher, when your alignment is off, when your foot movement is correct, when your breathing is right, etc. The dvd can show you the proper sequence, but cannot show you the connectivity from one stance to another, and even if it shows applications, until you have actually fought your teacher and/or your seniors, the dvd cannot show you how to deal with the changing conditions that any real fight will cause! The experienced people on here are not trying to insult you or tell you bad things, just to warn you that dvds do not fight back!!
