I justed backed up from my copy that i bought before kids get their hands on the original , what happens when watching it
1/4 way through it's muted no sound and say about cinavia protection and sound stays off
any fix for this ??? tried 2 different copy's same error

I Backed movie up , watched my copy and my friend and I notice it jumps to a scene further in the movie than jumps back than continues to play and you get to the scene that it jumped to
than later in the movies it jumps back to a scene that it already played. jumps back and fourth. ?? Why
