I decided to try to find a director’s commentary for a film. I thought it might be on the Bluray, so I bought both the disk and the drive. Notes here are:

• OSX doesn’t support bluray at all. You can buy software to play disks.
• VLC will support bluray, on both linux and OSX, but, most bluray’s are copy protected. There is various dubious bits of software to decrypt the disks, however, key revocation is built into both the disks and drive. Using a new disk revokes some access.
• MakeMKV will copy a disk (including defeating copy protection) for both linux and OSX. The resulting files are ~40G.

I was just amazed at how bad the whole experience is.
