Help figuring out how to encode this old DVD


I have a DVD I would like to backup properly encoded, below is the MediaInfo section relevant to the video. Could anyone tell me what processing I should do to it? I would like to use ffmpeg or handbrake (I'm on linux). Should I be using a deinterlace filter that changes the frame rate? I did some googling, and basically every thread contradicts itself.

Here is a sample https://workupload.com/file/XShefM3kyXd

Thank you!

What is the intended playback chain ?

Open it in a video player or editor which can play the video frame by frame.
Then you will see that there are 3 clean frames followed by 2 interlaced frames.
That is typical behavior of a telecined video.

Use Inverse Telecine to restore the video to 23.976.
