This is funny.  I bisected the problem to a line of JS in flashembed.js:
  var i=document.all
where "i" is an aliased variable.  The bug is that JSOP_SETLOCAL is JOF_DETECTING and JSOP_SETALIASEDVAR is not.

Finally, FF users can find out the answer to that burning question:

Test case wmv video failing

Verified error on Firefox 15 on windows Xp

Object area is blank on loading the page, it takes more than 30 seconds once the video is downloaded to appear.

Is not a matter of the browser waiting the video to download and then showing it after the download is finished
because if you use a video stored on your filesystem (without a server) it takes more time to appear and sometimes 
it doesn't even appear and only selecting the object in firebug on the HTML tab forces the video content to load.

Verified the error with the following three ways to include a WMV video (only one at a time) :
           <embed name="video" style="border:1px solid blue" type="application/x-mplayer2" src ="" width="800" height="600" showcontrols="1"></embed>
			<object type="video/x-ms-wmv" style="border:1px solid blue" data="" width="800" height="600">
              <param name="src" value="" />
              <param name="controller" value="true" />
              <param name="autostart" value="true" />
            <object type="application/x-mplayer2" style="border:1px solid blue" width="800" height="600" data="">
                  <param name="pluginurl" value="" />
                  <param name="controller" value="true" />

Test case wmv video with workaround

A workaround has been found duplicating the object (with very small dimensions to not interfere on the display), when more than one object is present on the page the first video loads OK and appears instantly on the page and only the last video included takes more time to load.
