I had a college sports team reunion and several teammates asked for a copy of a championship game. I still had the digital file, so posted it in a Dropbox thinking that would be easy enough for people whose hobbies don't involve computers.

Nope, I was spending too much time on tech support so offered flash drives with video files.

Nope, still too much for two teammates so after a phone call to understand what tech they had at home and were comfortable with, I burned them each DVDs.

It didn't get that far, but I was prepared to use my library's digital-to-VHS-to-digital workstation to copy them an old-timey VHS tape if the DVDs didn't work. The library even has a stash of never-unwrapped VHS tapes they'll sell you.
