Data Hoarder
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
Dvd Decrypter is worth using. Old but decent
As others have said MakeMKV and create a disc ISO it’s a full dump of the disc as is.
Use make MKV to compress them
DVD backup (Linux utility) for ripping the dvd into original VOB files and ffmpeg with appropriate switches (input: -i "concat:VTS_01_0.IFO:VTS_01_0.BUP:VTS_01_1.VOB:(etc)") for making it into an .mkv file with either the original codec (-c copy) or hevc (also -map 0 for all audio/video/subtitle tracks to be saved)
MakeMKV is the best option. It rips it directly off the disc exactly like it was put on the disc.
