Need help with inserting code in theme template

Hi, I’m new to inserting code into themes and because the site I’m working on bolivares.com needs the videowall on the home page only and there’s no place to insert a shortcode, I need to put it in the template. But where? I need some step-by-step instructions I can work with to pull this off. In case it’s of any help, the theme we’re using is a customized Max Magazine, and they want the video wall to replace the existing Meteor-slides slider (which evidently was installed the same way, so I don’t know how to remove that, either!), arranged so it will look like it does in this site: maestroknows.com I hope to have this worked out this weekend if anyone can help me. Thanks so much!
