As to customizing it to load just for a certain category, here's what I meant in my #4 suggestion earlier:
/includes/modules/pages/index/jscript_mywimpyplayerscript.php
Code:
<?php
if ($cPath== '3_10') {
?>
<script type="text/javascript" language="javascript">
....copy and paste wimpy.js code here
</script>
<?php } ?>
Change '3_10' to whatever the right cPath is for the one category you're limiting it to.
That's it. Put the file in the place specified. Leave your descriptions alone. No other coding needed.
