Buenas, estoy desarrollando una web XXX, estoy usando un script, y tengo problemas con el template, al entrar a la web mediante Internet Explorer 6 o 7, los videos están a la izquierda, cosa que no sucede con Mozilla Firefox, donde los videos están perfectamente centrados... una imagen de como se ve en IE:

No le puse censura a la imagen, pero si es necesario, me dicen

Aqui esta el CSS:

Y aqui el Index.tpl del template:


<center><div id='container'>

<!-- <<<< Head Section -->
<center>

<table width='980' border=0 cellspacing='0' cellpadding='0' id='maintable'>
<tr ><td class='intable' colspan=2 id='tdtop' align='center' valign='top'>

<?php
include ("logo.php");
?>
</div>


<br style="clear:both;" /> <!-- <<<< added -->
</td></tr>

<div id='categories'>

<?php



include ("scategory.php");

?>
</div>

</td></tr>

</tr></table>
</form>


</div>
<br>
<div id='topad'>

?>

</div>


</td></tr>

$tend=10; //last trade to show
include('partners.php');

?>



</div>


</td></tr>


</table>



</center>

En el index.tpl está la etiqueta "center" al parecer esto lo reconoce Firefox, pero no IE :S, me pueden ayudar

Gracias de antemano...

Saludos...

Raramente no carga la imagen; podes especificar la alineación del div o tabla en la que se encuentren los videos, de esa manera lo leerá seguro. Otra alternativa es especificar los margenes de la capa que tenga los videos.
