If you want to stop piracy then instead of streaming video -- offer MP4 downloads of the content. That way customers can watch the content when they want without having to worry about Internet access. Customers also don't want to be saddled with DRM restrictions and forced commercials when they are paying for content. The product that the pirates are offering is superior to what Netflix is offering. If I could pay a Netflix price for a safe marketplace that contains the same product that the pirates offer -- I'd do it. The content creators will never go along with that though so would rather saddle their customers with an inferior offering than that of the pirates and then complain about piracy.
Its all or nothing it pirates, ever hear of compromise? Because things like iTunes lets you down load stuff. Except the price is much higher the what pirates offer.
