4K Bluray, Blu-ray, DVD, UMD (I also have a lot of VHS tapes, in storage, no player.)
I love the Marvel Cinematic Universe. I also like the Underworld franchise, Star Trek franchise, Riddick franchise. Love most of all: the Tolkien movies from Peter Jackson, though some I love more than others and one I don’t like so much (Hobbit: Battle of the Five Armies.)
I use Emby Media Server.
I started using Trak.tv in early 2018.
UV, Vudu, Movies Anywhere, Google Play Movies. I have this … but don’t watch any of it there any longer.
