Planet Earth Disc 3 problems

[marchewd]

Has anyone tried to rip this disc? Discs 1,2 and 4 worked perfectly, but I cannot get it to rip either as a full disc or main movie. It says cannot read disc. I have tried three different copies on two different computers with two different BR drives. I was just curious if anyone has been able to back up their disc 3 of Planet Earth?

Thanks,
Dan

I have tried cleaning and even polishing the discs (with the scratch remover), all without luck.
