>I also started downloading Youtube channels that I really don't want to lose.
I'm doing the same.
I'm also considering downloading the TV interview series "Pričevalci" (means sth like "Eyewitnesses"). A historian who specialises in revolutionary violence (Slovenia post-ww2 and otherwise) does LONG (2hr+) interviews with old people with stories to tell. They're uploaded on the national radiotelevision website, but it takes some script-fu to download them (you have to sniff out the .m3u8 stream url and route it into an ordinary file using ffmpeg).
