I installed libdvdcss 1.2.12 (the latest version that offered a macosx version). I renamed the VIDEO_TS folder with the .dvdbundle extension. The system needed my password to authorize the name change but the icon didn’t change. I restarted and tried to open the folder with DVD Player but it gives me the error “The media type is not supported.”
The disc itself plays fine, but the copied VIDEO_TS files don’t.
