Strange problem using DOMDocument

[igmolicious]

I'm new here, so please forgive me if I offend any traditions, or anything. Anyhow, I'm trying to pull some news releases from RSS feeds, and meeting with some very limited success, as well as some strange problems. Here's the code that I'm using (more description of the problem(s) afterwards):

 

<?php
try
{
$doc = new DOMDocument();
$doc->load('http://feeds.feedburner.com/CityOfVillains-CommunitySite.xml');
//$doc->load('http://cohvault.ign.com/show_rss.php');
//$doc->load('http://www.cityofvillains.com/news/index.rdf');
$maxDisplay = 5;
$numArticles = 0;
$items = $doc->getElementsByTagName("item");

foreach( $items as $item )
{
	if($numArticles == $maxDisplay) { break; }

	$titles = $item->getElementsByTagName("title");
	$title = $titles->item(0)->nodeValue;
  
	$descriptions = $item->getElementsByTagName("description");
	$description = $descriptions->item(0)->nodeValue;
  
	$links = $item->getElementsByTagName("link");
	$link = $links->item(0)->nodeValue;
  
 	echo "<a class='content' href='$link' target='_blank'>$title</a>\n<br>$description<br>\n<br>\n";

	$numArticles++;
}
}
catch(Exception $err)
{
print $err->getMessage();
}
?>

 

The code works fine for the cohvault.ign.com RSS feed, but the stream connection times out on the www.cityofvillains.com feed, and it gets a 404 on the feed.feedburner.com feed. All 3 of these work fine, however, when browsed to. Am I missing something completely obvious?

404 means page missing, therefore the link is wrong.

404 means page missing, therefore the link is wrong.

 

I understand, however, browsing the exact same link, copied and pasted from the code, does not result in a 404 error.
