I get the same thing. One interesting thing is it rips all files except title01.mkv fine. Here are the sizes for the others:
14,643,727,788 title01.mkv
506,211,940 title02.mkv
151,006,602 title03.mkv
83,753,179 title04.mkv
116,717,883 title05.mkv
256,114,124 title06.mkv
348,043,724 title07.mkv
93,378,750 title08.mkv
The disc is pristine. I have tried to rip title01.mkv alone twice after cleaning the disc and both times it runs to completion and then gives an error message right at the end. It doesn't seem to be a defective disc - I have had defective discs before and what happens is it pauses and retries the disc somewhere in the middle and then craps out after spinning its wheels for a bit. With this one, it runs to completion without errors until "Remaining" is 0:00:00 and then it throws the error. Here is the log:

I will try the full disc backup as you suggest now...
