Now, if you do have problems with piracy, might I suggest this alternative: by the Blu-ray disc, thus paying the content creator for their work, and then download a pirated copy. At least then you can still avail yourself of the rights (such as format shifting) that they're trying to take away from you. Of course, this still rewards the content creators, thus encouraging further attempts to restrict your use of the material you bought with your hard-earned cash...
Would you feel morally justified in buying the DVD and downloading the Blu-Ray? It might send the message to them that DVD is worth more to consumers than these latest shenanigans.
