I am converting iso bluray files with MakeMKV.
Can anyone tell me how to tell where in the titles is the disk menu for navigation and language selection etc?

I want to be able to play bak all previews and menus - anyone know how to do this?
thanks

You cannot store menus in an MKV file, so your only option is to do a "backup", which copies the original collection of files onto your hard drive, with optional decryption.
