BLACK LINES IOS 7

I have a website that I’m working on. And I see black lines on several pages in the same place that the video is in. I’m already one through the process of elimination. I’ve contacted the developers of the theme I’m using and it came down to the fv wordpress flowplayer. Can you guy help me figure it out why the plugin is producing black lines in IOS 7 browsers? (Safari, Chrome)

the website is http://girlfriendsconf.com
