Youtube API Video Stream Broken on Site, Need Some Direction

Apologies for the vague title of my question. I'm just trying to figure out why a Youtube video stream on a friend's Wordpress site suddenly broke.

I'm trying to decipher it now, but I thought I'd post here to see if anyone could point me in the correct direction while I make heads or tails of this.

Thank you.

I think the same thing that happened to me may have happened to you.

As per your code it seems the API isn't correctly finding the playlist http://gdata.youtube.com/feeds/api/playlists/6549D4CA7BB99B16?v=2

In an attempt to fix my own troubled calls I added the PL to the Playlist ID : *PL*6549D4CA7BB99B16 http://gdata.youtube.com/feeds/api/playlists/PL6549D4CA7BB99B16?v=2

While googling this, I found a blog post referencing something about adding the ability to include the PL to the calls. apiblog.youtube.com/2012/08/playlists-now-with-more-pl.html

In my quick searches I didn't notice anything about them removing the old way of it sending the playlist ID.
