Error Loading RSS XML: Element 'channel' with namespace name '' was not found.

I have an exception here

var stream = e.Result;
var response = XmlReader.Create(stream);
var feeds = SyndicationFeed.Load(response); // IT IS HERE

The exception

Element 'channel' with namespace name '' was not found. Line 8, position 2.

RSS looks like:

 <rss xmlns:atom="http://www.w3.org/2005/Atom" version="2.0">
 <atom:link href="http://dallas.example.com/rss.xml" rel="self"
 type="application/rss+xml" /> <channel> <title>News</title>
 <link>http://www.samsung.com/us</link> <description>News</description>
 ...

http://validator.w3.org/feed/ says that "This is a valid RSS feed." (You can check it here http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fwww.samsung.com%2Fus%2Ffunction%2Frss%2FrssFeedItemList.do%3FctgryCd%3D101%26typeCd%3DNEWS)

So I have no clue whats happening... :(

Can we workaround to suppress some of the validation message of the SyndicationFeed class?

Thank you for ANY solution that will give me the chance forget about this exception!

Thanks to Michael’s answer, I was able to pre-process the offending XML (which is not under my control) to move errant atom:link elements:

private static readonly XName AtomLink = XName.Get( "link", "http://www.w3.org/2005/Atom" );
private static readonly XName Channel = XName.Get( "channel" );

...
var document = XDocument.Load( stream );
var channel = document.Root.Element( Channel );
foreach( var misplacedLink in document.Root.Elements( AtomLink ) ) {
    misplacedLink.Remove( );
    channel.Add( misplacedLink );
}

using( var reader = document.CreateReader( ) )
    return SyndicationFeed.Load( reader );

If you look at the results from the W3 validation you listed, it reads:

line 8, column 0: Undocumented use of atom:link

The atom:link element being placed before the channel element is causing the SyndicationFeed class to fail on load. You can test this yourself by downloading the rss feed xml locally, removing/commenting the atom:link line and running your code again. Without that line, the xml loads and the feeds are found. This has happened before with the SyndicationFeed class.
