JavaScript & Flash
I have a script that will rotate Flash Movies based on a timer(when the timer reaches 0 it shows the next movie). The script get the movie rotation from a XML file. There are also two buttons that will move to the next or previous movies. This script is working as it should.
The problem is when the timer reaches 0 and the script moves to the next movie I get a flicker(the space where the movie is rendered goes all white, I suppose while the next movie is loading). Can someone show/tell me how I can get rid of this effect? I am new to javascript all help is appreciated.
Here is a link of this script working:

this is just a simpleflash movie in different colors to show the rotation.
Here is the script:
<%@ Page Language="VB" %>
<script runat="server">

<script language="JavaScript" type="text/javascript">
