Ponyo feature fails to rip (not found)

[crios]

I attempting to rip Ponyo but MakeMKV can't seem to find the main feature. It can see all the trailers and a "making of" title but not the main movie. I'm using the mac version 1.7.9. Anybody know anything that can help?
Thanks

CellWalk algorithm failed (structure protection is too tough?), trying CellTrim algorithm?
Fake cells occupy 77% of the title - assuming fake title?

?Cells 1-7 were removed from title start?
Cells 51-51 were removed from title end
?Title #9 (1:42:54) was skipped due to navigation error?

Hi!

Title #9 (1:42:54) was skipped due to navigation error

Try cleaning the disc and then try MakeMKV again...
