Sorry to said I am shock people still watching DVD? and rip it to keep it?
Unless the film you want only in DVD format then it is different story.
I don't watch DVD since appear of Blu-ray and any film below 720p is a no go for me now.
How to watch DVD in 4K TV now! even in 1080p TV also is very bad quality.

By the way I do rip my blu-ray, I am windows user and below is my process.
1) Bypass the copyright protect using DVDFab Passkey 9.
2) RIP using VidCoder.
3) Meta data match using Plex
4) Playback at Apple TV 4K using Infuse with Plex Client
There are still some things on DVD not available anywhere else. I have a 4 season TV Show that is coming out next week that is not available on streaming or digital downloads that I'll be ripping. This thread is very helpful.
