If the problem people are having is Nintendo making contentID claims, Jim Sterling came up with a nice little workaround several months back that keeps them from doing anything. Since I agree that people who don't want spoilers won't watch an LP and an LP is fair use as far as I'm concerned, I wholeheartedly recommend looking into it if it will solve your issue. Even if it does mean occasional footage of totally unrelated things just to throw these companies for a loop.
