Legacy I see what you're saying, I think what Black and Fred mean to say, is in their experience, a video won't help much even in the technique of soldering, it's more of something you just have to learn by practicing (and failing).
If you're looking for general technique on soldering videos, actually I would check out youtube, I've seen some there before. I learned drag soldering small outline IC's by watching youtube videos.
Black, Fred and I all learned by failing. If you love modding, then try the mod. If you're trying to save a buck over buying a mod service, it might cost you in the long run if the mod install fails /if the controller gets broken.
