No, I haven't. For that, you either have to have a song on itunes or something that gets noticed, or you have to be approved for the content id program. Only the really big channels get this, because for us smaller channels not only are the odds of getting copied really low, and if they do, it'll get you less views. Besides, this wlil happen most often for music, and I already said that's taken care of with itunes/amazon mp3 or any other form of media store.
