How Do You Read A BD-Playlist?

I've recently encountered several movies which, after ripping, are broken into dozens of small pieces within the STREAM folder. Apparently the instructions for playing these back in the proper order are contained in the Playlist file? There seems to be no ryhme or reason as to the file sizes or filename order, it looks random to confuse us and prevent ripping. (Salt and Gladiator are two, and Gomorrah was slpit into two files). Does the Playlist contain the proper playback instructions for movies formatted like this, or is it another file, and how do we read it? I've given up trying to play all the files, catalog them, and figure it out manually, it takes DAYS!
