When confronted with what initially looks like a monstrosity (appears to put "Source Code" to shame), you can always simply use MakeMKV to make a "Full Disc" copy instead of a "movie-only" .MKV...
This is so called "structure protection" for blu-ray. It's also incorrectly called "java protection" as java is not always used with these discs. The disc contains a lot of "junk" content on purpose. This "junk" contents is properly authored, so unlike DVD, it's very hard to distinguish it from a normal titles. The current version of MakeMKV can't indicate which title is right one and which one is fake. This functionality is obviously coming very soon, as more and more discs use such protection.
So I'm trying to rip the Blu-ray I own for this (retail copy) and am struggling: there's no way I can see to copy the full disc, the link to the site that has the correct order is dead, and the one I tried a couple of years ago ended up being the wrong one. There's no Java protection, so that's not a solution. I'm at a loss here and I can't find the answer anywhere. Any suggestions?
