I believe both my parents' DVD and Blu Ray players have crapped out over the years. I still had a 24" iMac that would be a great DVD player for its size, but it didn't make the move. It's in my parents' garage now.
I think you can use a Wii as a DVD player if you find the right homebrew for it, but I haven't dug deeply.
Doesn't every blu-ray player, Xbox Series X, and some of the PS5s play DVDs?
