Couch distance and especially screen size can vary a lot. I can clearly see the difference between full HD and whatever resolution DVDs have at the 2~3 meter distance at my parents’. (43" full HD screen). Same goes for 4K vs full HD on my 60" screen.
In any case, my main point was that DVDs are no viable alternative to streaming services since all of them offer much better quality. If you really want to replace streaming services at similar or better quality, go for Blu rays.
It’s not a network file system. It’s a regular file system for hard drives, SSDs and such, which is used by default on Windows since Windows NT (that’s where the NT comes from - it doesn’t stand for network but “new technology”).
The implementation in Windows is closed source meaning the file system had to be reverse engineered to even work at all under Linux. Support nowadays is okay-ish, but as soon as you don’t properly shutdown your computer or use the file system under Windows, you will run into weird problems.
Also it just straight up doesn’t work for most games running under wine.
