The YouTube Blog announced that the new video player that they have been testing is now live for all videos that are embedded into any web pages outside of YouTube. You don’t have to do anything to trigger this change, but if you want to have the videos be played the old video player, just attach the rel=0 parameter after the URL. (i.e. http://youtube.com/v/dGAL2wWctII&rel=0)

I also noticed that the video player on YouTube.com now shows a loading indicator before playing the video.
