Google just introduced a completely rewritten embedded playlist players, ready for inclusion on any of your web pages that needs to display a series of videos in the same player, informed Jeff Posnick, YouTube API Team.
"The new embedded playlist player has a user interface that should be familiar to anyone using our current single-video player."
"Developer can try out the new playlist player right now by appending the version=3 URL query parameter to the URL they're currently using for an embedded playlist player. For example, if you're currently specifying http://www.youtube.com/p/E46798C874B35B7F?fs=1 in your
<object>/< embed> tags, using http://www.youtube.com/p/E46798C874B35B7F?fs=1&version=3 will play back the same playlist in the new player," explains Posnick.
Posnick said that "Google will be making the new version default on July 20, and at that point existing URLs will automatically trigger the new player."
Take a look at the example below:
