PowerPoint 2003 presentation with audio

[Demian]

I am trying to post a full screen PPT 2003 presentation to the web with audio.

I used code from Michael Koerner's PPT to HTML tutorial to get the
presentation to open in full screen mode. I added this function to script.js:

function FullScreen2()
{
if ( PPTSld.g_animUseRuntime )
PPTSld.document.body.pause();
ClearMedia();
var href = ( document.location.protocol == 'mhtml:') ? FULLSCR_HREF :
FULLSCR_HREF+"#"+GetHrefObj(gCurSld).mSldHref;
win = window.open( MHTMLPrefix+href,null,"fullscreen=yes" );
if( PPTSld.g_animUseRuntime )
win.document.body.PPTSldFrameset=window;
}

I also added this to outline.htm:

if( IsWin("PPTOtlNav" ) ){ LoadNav("OtlNavObj",UpdOtlNav);
parent.gOtlNavLoaded=true; parent.FullScreen2(); return }

For the most part, this works great and the presentation does open up in
full screen and plays the audio. However, the presentation also opens in the
original web window (the one with the outline and the slide show button). As
a result, the audio from the full screen presentation and the other window
BOTH play and overlap with each other, which sounds pretty strange.

My question is: How can I get the audio to play ONLY in the full screen
version of the web presentation and not in the other window?

I hope this question is clear. Any help would be appreciated.
