[Cin] FFmpeg 7.0 Merges DVD-Video Demuxer

[Terje J. Hanssen]

There has earlier been some descriptions on how to rip a DVD video with 
ffmpeg like this one
https://www.miskatonic.org/2020/05/12/dvd-ffmpeg/

I am curious  and excited to see if and what the publicized FFmpeg 7.0's 
DVD-video demuxer offers extra, hopefully also to preserve DVD-video 
menues(?)
