AACS (the BluRay copy protection system) is making a lot of effort to change what physical ownership means, and I'm pretty sure many TVs and players are working on "improving" on the privacy aspects too. One of the nastier aspects is that inserting a new disk can permanently modify your drive to no longer work with your player software, because the content industry no longer trusts that software.
