Alien (1979) - Lengths are not correct

[Gronnie]

Hi, I am trying to rip Alien (1979) and the lengths don't appear to be correct. In my player the lengths were 1:56:34 and 1:55:46 for the Theatrical and Director's cuts, but both titles on MakeMKV show as less than 1:55?

Turn on debug logging, and post the debugging information. There can be many reasons why title lengths will appear different, especially when a DVD or BD includes multiple versions of the same title, constructed "on the fly" by adding in or removing scenes.
