I like to watch TV shows in the background where I'm not going to be watching the screen obsessively, so I have several shows in 480P or sub-480P. There are also some shows where the "official" HD versions are just awful (most 90s sitcoms) or the show was made for 4:3 and has a different feel converted to 16:9 (MASH, The Wire).

Going beyond that though, I spent years on a really limited connection (2.6m down/400k up) and my instinct for saving bandwidth and storage space is still there, along with my need to pay it forward since I ain't no leech. I've become fond of making what I call "Bonsai Encodes", where the files are small enough to be sent over damn near anything. With mono Opus and VP9 video you can cram 45 minutes of perfectly watchable content into a sub-25mb file that'll play in Discord, with VTT subtitles even (though those won't play in Discord itself). Looks a bit like watching it on an old tube TV, but it's watchable.
