I was working on upgrading to the new version tonight on my live site, test site went swimmingly well. And I couldn't get the video player to display at all, bummer.

Then I noticed that if I turned off playlists, the video link would appear, but not the player. If I clicked on it, it opened in an Apture window, which I use on my site.

When I turned off Apture, the flowplayer3 player showed again.
