So yesterday 7/5/2020, I see there is a new change to the RMP. I don't remember how I got to it, but it was something like the * key or the "ok" key on a video file, and it popped up with an option that I could turn on a [repeat on] or something like that. there also was a shuffle option, I can't tell if it works or not. But at least I can repeat a single video now at least. What a mess they made of this. I have no idea what was wrong with the original interface where I hit play or re-play on a directory and it just played the directory completely.
There is a simple rule in programming and engineering: If it ain't broke, don't fix it.
