Thanks for your responses.

To clarify.
The Samsung is connected via HDMI to a TV.
All are disconnected from internet.
Regular DVDs play OK.
Some Blu Rays do play OK.
But for instance one that only plays the Blu Ray release but not the Blu
Ray Extended cut.

The one Blu Ray that will not play with the Samsung.
It will play on my PC that has a Blu Ray unit built in.
I am using NERO Blu Ray player to play it successfully.

Does this help identify a problem?

Sounds like you've been revoked.
The disk can revoke the keys stored in your drive without any
help from you or the internet.

I bought a used blue ray drive and stuck it in my Computer.
I checked out disks from the library and they played fine.
I borrowed my neighbor's "Avatar". It wouldn't play. And the
library disks now failed to play. SCREWED.
Seems that the subscription blu ray player apps get the recent
keys so they can play the disks.

I can't get excited about quality improvement over DVD.

Won't be long before you pay the $50 fee to watch the movie online
and they'll implant a post-hypnotic-suggestion that you've seen it.
Won't have to waste all that time watching it. Heck, they won't
even produce the movies any more. All they need are trailers...
and cash registers.

I was gonna use the drive for data backups, but the RE disks have
all but disappeared from stores. And they cost more than a USB flash
drive anyway.
