Heh, I'm getting back to physical media, and this big 4K TV is literally the first time ever where I've actually constantly noticed that DVDs might get a bit pixely.

(And even so, I usually blame not so great digitisation. Some transfers of old obscure titles were really sloppy, you really didn't need a great TV to see the problems. Original was a black and white movie, the DVD was a bunch of grey mush.)
