Make it exceedingly tedious to remove, but entirely non-intrusive for playback.
Coupled with credit card data and IP logs, it could provide specific targets for lawsuits. Moreover, with some of the tube sites where the owners are actually doing the uploads, it could very well help in proving that.
It has some downsides, of course. Password-sharing and cracking would implicate the wrong people, there'd still be ways to remove it, etc. Still, it could be a decent start.
(just thinking out loud here - nothing serious, zero research behind this)

Actually, add into this idea the subtle art of steganography, somebody could write a script to take a movie, and encode a user code - say a 256 byte hashinto every single frame.
Horribly difficult to remove if you don't know the hash you're looking for, and finding that out'd be horribly difficult.
But if you know the hash, horribly easy to check a movie for it.
