Good idea, and I don't think you really need to watch each clip 100 times. Maybe watch each one a couple times is really all you need, just make sure to listen to the cd soon afterwards. Pick one or two clips a day, and then focus on different aspects of kendo. I don't know antying about kendo, so i'll pretend you are watching tennis clips instead. Watch a few clips and focus on your forehand backcourt, forehand running, forehand net, back hand, serve volley, behind the back shots, under the legs etc etc. some other Paraliminals you might want to use are Instantaneous personal magnetism, and belief (install a belief that you are a superb kendo player) and even try new history generator, and install into your past of learning things quickly and effortlessly.
Many ways to skin this cat, and although watching a clip 100 times is one of them, it might not be the most efficient and relaxing way.
Good luck
