How do I embed a youtube channel that will show the latest video from that user?

Say for instance, the latest video on this page: <http://www.youtube.com/citizentube> 

Please don't tell me to go to <http://www.youtube.com/custom_player> because that page is dead. And please don't reference <http://code.google.com/apis/youtube/overview.html> unless you have a specific example. I've looked, haven't found anything. 

This is crazy frustrating. Apparently there was embed code right on the channel/user page back in 2010. But it is nowhere to be found now. 

Thanks,
Peter
