Youtue embed issue

Hello, when I embed a youtube video (i.e., typing the url directly) into a page or post, the Youtube Videos shows up no problem, however, there seems to be "black boxes" above and below the video. I have uploaded a screenshot here. Is this maybe a problem with the css? I am using the Simple Catch Premium theme, but I don't have this issue when I try other themes. http://www.vfaseattle.org/wp-content/uploads/2013/02/screenshot.jpg
