For what it's worth, if it was a PS4, they only require internet access the first time a Blu-ray is played. And, I don't mean the first time a specific Blu-ray is played, but the first time any Blu-ray video is played.
My guess is that Sony didn't want to pay the licensing fees for every PS4, so, the first time you play a Blu-ray, it connects to Sony to get a license. From then on, you can play them without internet.
