We have a high end 65" flat 4K, HDR/3D, TV in our stick house. In the cabinet it sits on is our DISH satellite receiver, Blu-Ray DVD player, and a high end (~$1000 way back when) VCR with Faroudja video processing circuitry and all kinds of video editing capabilities.
We watch movies on the TV from several HD and 4K streaming sources, the DVD player, and the VCR. The TV upconverts every lower resolution source to 4K resolution - including VCR and Super VCR (higher resolution VCR) movies. With all of the built-in image quality adjustments, video noise filters, and calibration adjustments of the TV we can tweak up any source materal to really make it the best that it can be when viewed in the home. My favorite VCR movies are in a boxed collection of the three tapes of the original aspect ratio wide screen versions of the first three Star Wars movies released to theaters way back when. Our TV really brings out the best in great classic VCR movies like these. As another poster mentioned earlier, VCR movies are now a very inexpensive way to access material from the past.
Streaming doesn't hack it when out boondocking in the RV unless you go the satellite route with an expensive plan ... so DVD or VCR or pre-recorded material is the way to go in an RV. Our RV'ing friends bring along on RV trips a multi-Terabyte USB drive loaded with hundreds of movies and other material for the evenings. Their USB drive of course plugs into and plays directly through their RV's TV.
FWIW, at home we find that an awful lot the (inexpensive) streaming material available is - for lack of a better phrase - junk.
