The videos by shi guolin are pretty neat but they don't break anything down for you. They show a monk performing the routine at full speed, then they show the same shot in slow motion so you can learn what he's doing. There's usually some extra 'bonus' material at the end of the video done in the same manner, full speed then slow motion. The particular one I have is of some of the drunken stuff, at the end of the video there's what I take to be some drunken 'training' manuevers that aren't in a routine, just various monks going through warm ups or something similiar.
As far as 'training' goes, there's no instruction, just some information about each monk performing. It's not like a virtual instructor or anything, all you have to go in learning the routine is the slow motion segments. The full speed segments will show you how the routine is 'supposed' to be performed. As far as the breathing involved with the set, the applications of the routine, or any training that may be necessary for some of the moves i.e. a head kip is not covered. Maybe there's a seperate tape that covers those things but that's beyond my experience.
They are good for reference and it's always cool to watch the monks in action.
Blessed are the flexible, for they shall never break under the pressure!
