I've been watching movies on VHS. Yes, I actually have one of those rare items, a working vcr.
There are a number of movies I just held onto the tapes instead of replacing with dvds (or worse, digital). These are shows I enjoy, but can go 10+ years between viewing. Last night I watched Mr. Holland's Opus. Thoroughly enjoyable, but no need to see it frequently.
Regarding digital copies; I just like having something physical I own and can watch any time, even if my internet is down. I'm the same with books; if I really love it, I want a paper version in my library.
Side note: positive aspect of being an empty-nester is I can have a crabby day and not bother anyone else.
