how to remove controls from embedded video?

Is it actually impossible to remove the UI controls from this embedded video?
http://www.w3schools.com/html/tryit.asp?filename=tryhtml_objectmplayer

<param showcontrols="false"> 
<param uiMode="invisible">

...showcontrols="false"...

does not hide the controls - contrary to natural english meaning of "show controls"

EDIT: --THE FOLLOWING WORKS & IS CROSS-BROWSER (until IE10)...
EDIT2: --BUT THE FOLLOWING ALSO SEEMS TO CAUSE NEVER-ENDING-SENDRESPONSE-STATUS WORKER PROCESSES (SEE https://stackoverflow.com/questions/16790199/iis7-5-wmv-requests-cause-many-workerprocesses-in-never-ending-sendresponse-stat)

Taking your W3Schools example code -

<!DOCTYPE html>
<html>
<body>

<object width="100%" height="100%"
type="video/x-ms-asf" url="3d.wmv" data="3d.wmv"
classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6">
<param name="url" value="3d.wmv">
<param name="filename" value="3d.wmv">
<param name="autostart" value="1">
<param name="uiMode" value="full">
<param name="autosize" value="1">
<param name="playcount" value="1">                              
<embed type="application/x-mplayer2" src="3d.wmv" width="100%" height="100%" autostart="true" showcontrols="true" pluginspage="http://www.microsoft.com/Windows/MediaPlayer/"></embed>
</object>
