I see where things are being matched, but how are they being replaced? What you really need here is preg_replace_callback(), probably.
<?php
$result = preg_replace_callback('/\{([a-z]+) ([0-9]+)\}/i','callback',$yourtext);
function callback($matches)
{
//$matches[1] is movies, cartoons, textlinks, etc
//$matches[2] is the number that was matched
//this function should return the string to replace
//{movies 20} {cartoon 10}, etc...
}
?>
