Using that guide it will create an unencrypted BD Structure on your HDD (no need to burn to a physical media) if you just uncheck the "Use ImgBurn" option and then select "Blu-Ray" instead of "Blu-Ray and Burn" (see the pics in the other thread). The resultant BD Stucture can then be imported and played in MC just fine + you have the option of then later burning it to a physical disk if you so want. Clown BD also lets you create a single "M2TS" file instead of a "Blu-Ray" but the downside is you will lose the chapter marks (if you care). MC will still let you skip fwd (30sec) and back (10sec) using the arrow keys.
I did play with MakeMKV at one point but as per the other thread can not advise on the best "guide" but there are plenty out there if you search. MKV's will let you include chapter marks.
None of these methods preserve the "Menu" and are all focused on just ripping the main movie and associated Audio, Subtitles, Chapter marks. So if there are "extras" that you want or need then you need to create a separate conversion for them.
ClownBD is "free" (really a front end for a bunch of other tools). Give it a go - nothing to lose!
Edit - start with a simple disk with no Forced Subs to get the hang of it (these are nice a simple to convert).
