Always something, no matter what! In moving content over from the PHP-Fusion setup, some videos wouldn’t play after adding them to posts. Specifically, the Bruno Mars concert video clips. they play fine on the old site. On here, some play, some seem to keep buffering but never complete.
Long story short, I put them up on YT on my “Royce” channel and link to it. All seems to be good.
So… YT will be the first choice for hosting the video. Private, not public, as appropriate.
