I can play only one dvd on my brand new MacBook Pro
The DVD Player app on MacBook Pro launches but the movie does not come onto the constantly black Viewer screen. But I can still watch one specific DVD. All others are this black screen. It seems like something happened Friday when this movie (Ingmar Bergman's Seventh Seal) loaded. Since watching that DVD, no other DVD is watchable, only Seventh Seal.
Can anyone tell me how to correct this problem?
MacBook Pro 13″, macOS 11.6
