I made a ISO of the BL with a Aurora Blu-ray Copy and tried to open it with MakeMKV.
Seems this does not work because there are some hidden keys on the BL that are not copied with Aurora.
I welcome anyone with any input that might make this work.
and no, I no longer have the original BL.
Here is an updated...
I tried several more times(Mac) with the original BR but still could not get it to work.
Then I tried it on a PC (Windows 7, Same BR Player, Same BR disc) and all worked fine.
This is the 1st and only time I have run into a problem with this software and my Mac.
Just in case anyone out there has the same problem... Try it on PC
