http://www.clipconverter.cc/ Use this website to take YouTube URLs and download them into .mp4s for personal use. It should work w/ all videos, even those that are region blocked. Once a video is completely blocked or removed, then it won't work. If it doesn't work, then PM me. Also, just to be on the safe side, use an adblocker w/ your browser, just in case there are annoying pop-ups.
I've been doing this to all Don live and TV performances just in case they get removed, which is a strong likelihood.
