Why are you still using DVD Decrypter? It's been abandoned since 2005.
Over the last couple weeks there's been a few threads of people insisting on using DVD Decrypter. I was wondering why are people still using it? Datahoarding tends to attract relatively technical people, so there must be some reason to keep using software that hasn't been updated since Windows XP was modern.
MakeMKV seems like the better option in every use case except full backups. However a full DVD image can be made with any imaging software or even just dd. Any player that can handle the DVD menus from an ISO is going to be able to decrypt during playback.
I use it to rip everything into one big vob then feed the vob through handbrake and use hardware accelerated encoding using my 3080ti to encode the movie in ~3 mins
works great for Movies but TV shows are much more complicated.
