How would a company go about being certain of this, do you think? I can't think of a way to do it with uploaded content that doesn't have a nasty error rate. Obviously it becomes trivial if you take the Netflix approach and source everything from the owners directly, which means working only with the biggest providers who have legal departments and such. With restrictions like this, even SoundCloud can't exist - almost everything on there is a derived work!

Have I missed something? Can you help me understand how a site can be certain it hosts only original or otherwise authorized content without taking a Netflix-type approach? I would love to be wrong, and for there to be an easy, cost-efficient approach that offers a suitably low error rate and enables protecting content creators while preventing abuses.
