First I thought you just can't do that. But at second thought you might use a trick...
Create another page just like a local video page and link to it in the video-links layer.
Remove everything from the new page.
Place a button on that page that links to the home page, but change the "Open link" property to "Parent frame".
Add a small script that auto-executes the link when loaded to the placeholder body code.
Code:
<script>
(function(){var s=document.getElementsByTagName('script');return s[s.length-1];})().parentNode.parentNode.click();
</script>
See example.
