What to do with DVDs?

[PolypGrunterPulpit]

I've been officially living under a rock for several years thanks to babies, illness, blah blah. Do people still use DVDs or is everything Netflix and Amazon now? DH and I have so many DVDs and I'd love to get rid and just have digital copies. Is this even a thing? Can I convert them? Or do people just buy a subscription like Netflix and everything you could want is on there?

I was hoping you'd get some answers as I'd like to know too.

My own probably old-fashioned thoughts are:

You probably can't convert them because they will be copy protected.
Some platforms might have exclusivity deals with some film studios, so the only way to know if your films are on Netflix, Amazon etc is probably to look.
If you chuck away the individual cases and put the disks in the sort of CD/DVD cases that hold 32 (or whatever) disks in thin plastic pouches, arranged like the pages of a book, they take up much less room. (But you are still in the land of hopelessly old-fashioned like me).

I still have a blu ray player as I have quite a few yoga DVDs that I like to imagine actually watching/doing one day
