Not sure if you already got your answer, but the dropshadown is not part of the flash movie. You need to incorporate the dropshadow into your design and get it in place via html/css.
This is an old thread, but here is the code in case anyone else needs it. This will pull in the subnav for the section you are in.
<ul id="nav_sub">
<?php
if($post->post_parent)
$children = wp_list_pages("sort_column=menu_order&depth=1&title_li=&child_of=".$post->post_parent."&echo=0"); else
$children = wp_list_pages("sort_column=menu_order&depth=1&title_li=&child_of=".$post->ID."&echo=0");
if ($children) { ?>
<?php echo $children; ?>
<?php } ?>
</ul>
