also its not just pure “compatibility”, but I had a time when I played vids to my TV over an old laptop (from around 2015). Worked like a charm. But some x265 vids went into full-on stutter mode in scenes where a lot of stuff was happening… was more a nuisance than a dealbreaker, but still, preferred x264 versions if I could get them
maybe our generation (if we’re even the same, lol) could just hide our boredom better :D But deep down we all needed that teacher who could keep us engaged… but who knows… :)
