I'd like to add some comments here - it's my first time. I'm a web developer and
searched hard - this one seems the most appropriate.

It's not just the volume control which kills a WMV image embedded in a web page.
I use the following code to call a file which dishes up the correct media for
browsers. Here's the code:

<IFRAME style="border:1px solid #CCCCCC" ID="mediaFrame" name="mediaFrame"
FRAMEBORDER=0 SCROLLING=NO
SRC="Content/mediaLoader.aspx?movieName=4530&movieCaption=Life%20Full%20Of%20Opportunity&movieAutoStart=false&audioImage=4530-audio-only.jpg"
width="240" height="196"></IFRAME>

The code sent to firefox by medialoader.aspx is as follows:

{					
	document.writeln ("<table width=240 height=196 cellpadding=0 cellspacing=0
border=0><tr><td colspan=3 valign=top width=240 height=180 background=\"" +
IMAGE_PATH + audImg + "\">");
	document.writeln ("<div id=playerDiv style=\"visibility:hidden\">");
	document.writeln ('<OBJECT ID=mediaPlayer7 ');
	document.writeln (' CLASSID=CLSID:6BF52A52-394A-11D3-B153-00C04F79FAA6');
	document.writeln (' standby="Loading Microsoft Windows Media Player
components..."');
	document.writeln (' TYPE="application/x-oleobject" width="1" height="1">');
	document.writeln ('<PARAM NAME="AutoStart" VALUE="false">');
	document.writeln ('<PARAM NAME="uiMode" VALUE="none">');
	document.writeln ('</OBJECT>');
	document.writeln ('</div>');				
	document.writeln ("</td></tr>");
	document.writeln("<tr><td width=44 height=16 background=\"" + IMAGE_PATH +
"mediaPause.gif\"><img id=buttPlayPause src=\"" + IMAGE_PATH + "mediaPlay.gif\"
onclick=\"playPauseMovie()\" style=\"CURSOR:POINTER\"></td><td bgcolor=white
align=center class=text9px width=152 height=16>" + movCaption + "</td><td
width=44 height=16><img src=\"" + IMAGE_PATH + "mediaStop.gif\"
onclick=\"stopMovie()\" style=\"CURSOR:POINTER\"></td></tr></table>");
	Player = document.mediaPlayer7;
}

Anyway, Firefox doesn't use our custom video controls (which is fine) but it
fails whenever we use any video controls. details as follows:

1) WMV image disappears while audio keeps playing.
2) scrolling the page even by 1 pixel brings the image back.

This says to me there's something wrong with drawing in overlay mode when the
player controls are touched.

Once you've scrolled just a fraction, using the video controls does NOT make the
image disappear.
