Can we insert html code into coursepress pages?

Hi guys,

Is there a way to insert html code into a coursepress page? Basically we want to have a youtube video but without the related videos showing and using the current youtube link it doesn't do this.

We want to be able to insert the iframe, can we do this at all?
<iframe width="560" height="315" src="" frameborder="0" allowfullscreen></iframe>

Many thanks
