the newly purchased movie would check the key and not play.

The Sony PSP handheld game did something similar. I purchased the Ratchet
and Clank game, put the UMD disk in the PSP and the game wouldn't play
until I did an OS update. People had been hacking the PSP and Sony while
providing some new web browsing features to justify the update also made it
harder to hack. Since the game didn't need any of the web features my guess
is that this was Sony's sneaky way to force an
  unnecessary ( for me ) update
