Hi,
the "top" position is only defined to display a menu or a search engine, like your screenshot.
Between the pathway and the begin of content there is any position defined to display your module.
To place your banner module, create a new unused position on index.php file. Localize a comment named "content" at line 160
<!--begin:content-->
<div id="content">
<?php mosMainBody(); ?>
</div>
<!--end:content-->
And write this :
<!--begin:content-->
<div id="content">
<?php mosLoadModules('user5', -3); ?>
<?php mosMainBody(); ?>
</div>
<!--end:content-->
After your header rotator, place in "user5" must appear correctly.
