Finally, using the software MakeMKV (paid, 30-day trial), you can play Blu-ray videos under OSX.
So certainly, not everything works right out of the box, but there are solutions!
Note, support for Blu-ray data was he supported by OSX.
So, I have not yet tested under Windows, but it is noted that following powerDVD 9 which allows playback of 3D Blu-ray comes with the product, so use under windows should not be a problem particular.
I am very satisfied!
