FeedWordPress conflict with quick text filter – HELP!!

I’m trying to get feedwordpress working along with another quickie plugin that I wrote to prepend all outgoing urls with my click tracking service. The plugin is this:

<?php
/*
Plugin Name: Quickie Text Replace
Version: 1.0a
Plugin URI: none
Author: You, fool.
Author URI: none
Description: add xclicks code to URLs.*/

function xclicks_out($content)
{
$content = str_replace('href="http://', 'href="http://x4.xclicks.net/sc/out.php?s=3708&o=http://',$content);
return $content;
}

add_filter('the_content','xclicks_out');

?>

The problem is as follows:

When I have just FeedWordPress activated, it (FWP) works fine.

When I have just the Quickie Text Replace activated, it works fine.

When I have them BOTH activated – the FeedWordPress works, but not the Q.T.R.

Why would these two not play nice?

Also, any suggetions on how to make it so that if I want to replace a few more strings, I wont have to create new functions (replace 1(), replace2(). ) I image an array os sort.
