This is not a plugin, this is an error in the coding. You can check it yourself by inspect element using Firefox.
This is the code of the control buttons ( start , pause and stop)
<map name="map1">
<area shape="rect" coords="0,0,45,26" href="#" onclick="lightStop()">
<area shape="rect" coords="47,0,90,26" href="#" onclick="lightPause()">
<area shape="rect" coords="92,0,135,26" href="#" onclick="lightPlay()">
</map>
While if you check the function lightStop() or lightPause() or lightPlay() you'll observe the error.
function lightPause() {
swapImage('document.controls','document.controls','../common/controlspause.gif','swapImage1');
document.presentation.DoPause();
document.swapImgData[1]=document.controls.src;
return false;
}
you'll notice an error raised
Uncaught TypeError: undefined is not a function
So in simple words, you don't need a plugin this is some coding error in the site.
