I am trying to rip Go from 1999. My DVD is single sided but does have an aspect ratio menu that opens first and asks if you want to watch widescreen or full screen. Haven't run across this before with MakeMKV, which rips the one movie file available as a 4:3 mkv file. I imagine I have to use VLC, open the DVD, choose widescreen, and then via some method rip the movie after hitting Play, which I have never done before.

So, is it possible to rip the widescreen using MakeMKV or any other suggested tool?

First time I heard of such thing. Assuming the film is originally widescreen as usual, does the "fullscreen version/mode" look "squeezed" or cropped? (Assuming it's not the other way round -- that the "widescreen version/mode" is just a cropped fullscreen "fattened"...)

Knew I forgot to mention something. Full Screen is cropped via pan'n'scan.

If it is really pan and scan (i.e. the "scan" is not always the center part of the widescreen version), then it's probably "implemented" with multi-angle.

I have no actual experience with multi-angle DVD but I do know that they exist. It's just that I never thought that it would be used to provide alternate version of a different aspect ratio -- assuming that's the case here.

No idea how well MakeMKV support multi-angle DVD. Have you checked if by any chance the two angles/versions are already in the remux? (I think they would exist as two video tracks/streams just like audio tracks of different dubs.) If not perhaps you want to see if other tools like ffmpeg or mkvtoolnix would include the widescreen one when remux. (You can / would need to make a decrypted backup of the DVD with MakeMKV first; or some libdvdcss frontend like dvdbackup.)

P.S. IIRC by default ffmpeg would only include one stream per type (video, audio, subtitle...), so you'd probably need some -map argument to include (or select) the widescreen version. Either way, you can definitely use ffprobe to confirm whether the VOBs carry more than one video stream.

It is true pan'n'scan with the crop going from side to side as deemed necessary by whoever does those things to get 4:3.

I will install ffmpeg and see if I can get ffprobe to work. First and only time I tried ffmpeg was nearly twenty years ago, and I couldn't get it to do what I wanted. At least not without spending a lot of time learning to do something once that wasn't all that important.

The entry for the disc on blu-ray.com suggests it is a dual layer disc. I would guess that there is probably two titles on the disc, one that is the widescreen and the other that is the 4:3 pan & scan.

Does MakeMKV's log suggest that MakeMKV is removing any titles when it loads the disc?
