MakeMKV cannot open the Blu-ray disc "The Fall of the Roman Empire."

[dejoro]

Hello from France,

MakeMKV cannot open the Blu-ray disc "The Fall of the Roman Empire."

The Blu-ray drive spins, but it displays "No disc."
My drive is a PLEXTOR BD-RE PX-LB950SA.
I even bought a second copy of the "The Fall of the Roman Empire" Blu-ray, but I’m encountering the same problem.
Thanks for your input.
Denis
