Open YouTube video in new window from slider in "Product" theme.

Let me start by saying I'm new to Wordpress. I need someone who is familiar with the "Product" theme. I can't find a way to edit a slide within the slider in that theme, so that a linked YouTube video will open in a new window without dumping out of the site. Right now the only way to get back to the home page is with the back button. WPMU-Ian from India was not able to help me because he gave me general instructions which were not relevant to the "Product" theme. Any step by step help from someone who looks at the "Product" theme for a newbie will be greatly appreciated.
