embedding youtube video in flash with as2 - problem with black bars

I have successfully embedded the youtube video in my flash code with:

//create area to put youtube video on screen
this.createEmptyMovieClip("reason1_video", 10000);
reason1_video._xscale = 60;
reason1_video._yscale = 60;
this.reason1_video.loadMovie("http://www.youtube.com/v/PUt7Kw9Q_Qc?hd=1");

However, the video plays with black bars on top and bottom even though it plays without those directly from youtube:

Even if I take off the scaling, it still has the black bars. How do I get rid of them?
