video is not displayed using this code from youtube in a joomla article:<object width="480" height="385"><param name="movie" value="www.youtube.com/v/wMWDJz5Z-Rg?fs=1&hl=en_US&rel=0">www.youtube.com/v/wMWDJz5Z-Rg?fs=1&hl=en_US&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385">

if I use this one from another video it works,
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="480" height="385" codebase="download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0">www.youtube.com/v/Gp1Frb4RWNs&hl=en_US&fs=1" />

What can be wrong ?, we just copy and paste from the embedded field from youtube into hmtl

After review, fail only happens  in IE8, Ffox 3.6  and works in Chrome 5, any comments?

But I cannot see AllVideos plugin in your site...

mmm strange, plug-in is there with version 3.3, since it didn´t work I  use the line {youtube}wMWDJz5Z-Rg{/youtube}and it works, I guess is fixed
