Multiple players

I am getting multiple players at http://christineamsden.com/wordpress/?p=2116 The post in the blog aggregator http://christineamsden.com/wordpress/?page_id=200 it works fine, but when I open just that one post I get two copies. I am not using jetpack. I do not see any obvious javascript breakage. I am using hmp 2.1
