Create 2 new html pages. One html page will have your left column of videos and shoutbox. The other will hold the frameset, call this one index.html and host it on the root of your server. In the frameset html page, set one frame to read '/' and the other to read the html file you are hosting.
Something like this for the index.html... (I just grabbed this from a site and edited it).
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta name="robots" content="noindex,nofollow">
<title>BoneMan's bone lair...</title>
</head>
<frameset cols="*,200" framespacing="0" frameborder="no" border="0">
<frame src="/" name="leftFrame" frameborder="no" scrolling="yes" id="leftFrame">
<frame src="/right_frame.html" name="rightFrame" marginheight="0" frameborder="no" scrolling="no" id="rightFrame">
</frameset>
<noframes><body></body></noframes>
</html>
Then you need the black page with the player and shoutbox... (right_frame.html)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title>BoneMan's Vids and Shouts</title>
</head>
<body style="background:#000;">
<!-- VIDEO PLAYER -->
<!-- SHOUTBOX -->
</body>
</html>
EDIT:
I just had a thought '/' might not work, you may have to host the folders one level down in hfs. In a folder or something.
