I personally own a lot of dvd's and blurays, but it's been a while since I actually watch them in that format.

I just rip the disc to my harddrive, demux/convert what i want (usually just the main audio to flac), then remux to mkv and store the result (video + audio + eng subs + commentary tracks). Then just watch in kodi/plex.

Dealing with the actual discs etc seems just weird, neither dvd nor bluray as a media was never any fun to use. Using a remuxed copy of a tv series i'd be half way through an episode by the time the trailers and fbi warnings stopped playing on the disc version.
