First - MakeMKV has had a feature for some time now to try to guess the correct play list. It is discussed in this topic: http://makemkv.com/forum2/viewtopic.php?f=8&t=14330
It involves having the Java Runtime Environment (JRE) for your operating system installed. You can get that by going to java.com, the official website for Java. Personal recommendation: Do NOT install "web integration" or "browser support". It is not needed for the JRE to work with MakeMKV, and it is one less potential security hole when surfing Internet.
If the JRE is set up properly, AND you insert a Blu-Ray disk with "fake playlist protection" (i.e., something sold by Lionsgate), the log window will show a message similar to:
(this will not appear for non-BD disks or BDs that do not have "fake playlist" detected)Using Java runtime from C:\Program Files (x86)\Java\jre1.8.0_121\bin\java.exe
If MakeMKV can sniff out the main feature, it will move its play list to the top, with a comment of "(FPL_MainFeature)" next to it in the selection window (left part of screen).
Hint: To unselect the titles you do not want, put your mouse over the selection area, and bring up the "Context menu". The context menu has 3 options, "Toggle item", "Select All", and "Unselect All". Chose appropriately. Windows users can use the RIGHT click button on their mouse, or use the "context menu key" on their keyboard. This also (usually) works for Linux, and with multibutton mice on Macs, but single-button mice usually require you to use the Ctrl (or Control) key when you click.
If MakeMKV made an incorrect choice (it can happen), let Mike know about it - information on how to do that is found in the first link in this message.
Failing the above (and if you have a DVD), do a search for the title of your disk first. There are over a hundred different movies being discussed at various times on this forum, some of them having 5 or 6 different topics. And these disks have different play lists that are "correct", depending on when and where you bought them.
Titles with short words are hard to search for, because the forum software doesn't index words shorter than 4 character. Google can be your friend here, and you can search for things like "MY MOVIE TITLE MAKEMKV" and you'll probably find the topic on this forum that is discussing the various working playlists.
