3D iso mvc = untouched, 1:1 backed up copy uses .m2ts and .ssif (3D) files within a bdmv folder. Just different containers (MVC MKV vs. ISO vs. BDMV folder structure).

Forgive my ignorance but now I'm really confused?
This is how I understand it:

An iso is a container with all elements of the original disc placed inside the iso container in its original file structure retaining complete menu.
An mkv is a container that allows specified elements of the original disc only and cannot contain all of the original contents so no menu will be present.
Folder structure has no container at all and also maintains the original menu.

3D iso mvc: Huh?

What is an mvc? Specifically, an mvc inside an iso container? Is an mvc like an mkv? Is it a container? Is this like a container inside a container or something? What's the upside?
Thinking about it, are you guys ripping multiple mvc's and gathering them up in another container (iso) so you have a complete rip?
Why would you do that? Why not just use the original m2ts and ssif? Why would you have to convert those original files to anything else?
