Yoga DVD played on Plex advice plz

Hey all, I have a set of 4 Yoga DVDs that I’m wanting to share for myself and a friend. Don’t think anyone else will be interested and I’m not quite sure how the files are going to be taken off the dvd. I read up on it last week and it’s either make MVV or Handbrake to convert from DVD to pc. However because there is 4 dvds I’m not quite sure what will happen with the files. Not sure how they will be named or anything.

I could make a new directory/library called Yoga dvd and just give us two access but could someone guide the best way to keep the 4 disks/ content in order or in the same order they play on the dvd please. At the moment I just have them as 4 iso files.

Thanks.
