Usually MakeMKV finds the right file by itself, that's when I used to free preview anyways. It usually is the biggest file with 1:30min or 2hrs. (Change the view) tab.
Yea I know that the largest file size is the movie. There are sometimes discs that contain multiple playlists of the main movie. This is where it gets confusing.

I use BDInfo to find the play list. If their is more then one long play list I play the movie to find the exact length and then their is only one play list that matches the same length.
I did a little bit of reading reading about this online. It's a type of copy protection called Screen Pass, where they put a number of fake playlist to discourage ripping. AnyDVD HD can supposedly bypass this and find the proper version of the movie.

If you already played the movie why bother with the rip?
They probably weren't playing the entire movie. It's a common trick to play the main title for a few seconds in order to pause and determine the main title's run time (all the way to seconds)
Yes, Hunger Games, Star Wars, John Carter, and plenty other discs have *tons* of possible looking main titles. In my experience, some have 2-3 (out of the 20+) with the same run time as the real main title's run time. Usually, best method is a google search. Just use "Movie Name which title makemkv" and look within their forums. Not many movies have such problems
Yes, several discs have multiple titles with the exact same runtime (and same number of chapters). But sometimes you can look at the times of several chapter marks and distinguish them that way.
Also, AnyDVD can usually tell you which title number is the correct one (in its info window after it has scanned the disc). However, even AnyDVD failed to find the correct one for me on one recent disc (The Last Stand).
I agree that the best way (as long as it has been a few days after the disc has been released) is to look in the forums or google for the right playlist number.
Scanning the disc with AnyDVD HD and checking the status window is the the only easy way to tell at the moment, without searching online or checking each playlist.
BDinfo or the list on the link posted will not be correct with these Screenpass discs, there are multiple playlists with the correct length (some out of order) and the longest playlist will not be correct either.
They're probably all valid playlists. I usually just pick the first large file with chapters. The additional large files are probably slightly different versions of the same movie with deleted scenes added in or slightly different takes of the same scenes. Since I usually haven't seen any of the Blu-Rays I'm ripping I won't know the difference. So far, picking the first file has worked out for me. I generally perform a spot check to make sure I haven't selected the wrong soundtrack or subtitles and rerip, if necessary. I can't recall the last time I've had to rerip a title so my system seems to be working out pretty well.
No, on the discs with this kind of protection, they are NOT all valid playlists. That is the point. Some of the invalid playlists have repeated scenes, missing scenes, a text warning inserted, out of order scenes, etc.
Yes, I can confirm just picking the first large file or track in MakeMKV will not work with Screenpass protected titles, the scenes will be completely out of order and unwatchable.
Its nothing to do with how a system is setup, MakeMKV has no idea which playlist is correct, maybe in future updates it will handle these discs correctly.
For now you have to either use another program (AnyDVD/DVDFab), search online or check each correct length playlist to determine which is correct.

This just rang a bell with me. I had ripped a movie a while back and I recall that for some strange reason I decided to rip one of the other large files further down the list instead of the first one as was my usual practice. When I played it back it repeated portions of the movie or jumped ahead and then back and was basically all over the map. I re-ripped it, but this time I chose the first large file and playback was fine after that.
Here is what I do with MakeMKV: I first play the movie in regular BD playback software and write down the exact length of the film and chapter counts. Then going through the playlist to find the one that match the exact film length. Typically there will be only one playlist that matches the exact film time. Use the chapter count to quickly weed out the wrong one. It is not that hard.

Again, you are missing the point. Some discs (currently, a relatively small number) are protected with playlist obfuscation techniques, and there will be multiple titles with the exact same times and chapters. Some will be "fakes" that will not play the movie correctly. You cannot tell which is which just by time and chapters.
I'm not sure why some people in this thread are having such a hard time understanding this.

Not only that, but some movies will have a different correct playlist depending on the version of the disc. For example, the retail and rental versions will have a different correct playlist.
Like others have noted and I tried to point out with the google search, I search for the title on MakeMKV's or AnyDVD's forum for what others have found as the correct playlist. I've found this to be very reliable. Also, as others have noted, AnyDVD HD will tell in the status window. But, sometimes it lists multiple good playlists.
Examples of titles using Screenpass are:
Expendables
Expendables 2
The Hunger Games
Source Code
Twilight Breaking Dawn
Three Musketeers
Seems to be popular on Lionsgate titles.
Also, some Disney movies like Tangled and Brave have multiple playlists for different languages. For these, I've found the first one listed in MakeMKV is correct for English.
I've also viewed the individual segments to determine differences.

among all the discs I ripped, I have yet see one that has more than one playlist of the exact same time length and chapters, yes, I saw some discs have more than a dozen fake playlists but the correct ones are very easy to spot. you are welcome to show me one example you claim existed.

Animated movies like Pixar movies are the worst culprits. The problem isn't always fake playlists, but often different "angles". Often what this entails is slight changes to the text in a movie (like the words on a newspaper) based on which language you choose (see here ). You may see multiple playlists with the exact same length, same chapters, and same audio selections. It can be pretty frustrating. IIRC, I had issues with Finding Nemo and Bolt.
That is certainly not the "worst culprits", since the movie is fine even if you choose the "wrong" playlist, you just have some parts with different language text or credits.
The worst culprits are the ones with playlist obfuscation protection -- if you choose the wrong playlist, the movie is unwatchable. I already gave one example, and I see someone else listed several.
