In the (currently) 220-page thread in the Samsung support forums virtually
everyone that's mentioned it has said they've had it connected to the
Internet, for the simple reason that Blu-ray DRM requires connectivity/
updates in order to play newer discs.  One poster explicitly mentioned they'd
never connected or updated their firmware and things were fine, but that
doesn't really narrow the cause down.  In any case Samsung is now RMA'ing
players automatically if people call in with a problem.
