It looks like a bug is back where a dynamic playlist with one element doesn't automatically loop (repeat). User "shx" has found a fix. Here is the original thread which was marked "solved" and probably will not be checked:

I found the offending line of code in flowplayer.playlist-3.0.6.js
var manual = self.getPlaylist().length <= 1 || opts.manual;
I had to change this to '< 1'. Now it works with a single item in the playlist.
