Code: 
    Private Sub Process_Info_Node(ByRef feed As RSSFeed, ByVal XMLNav As XPathNavigator)
        Dim XMLInfo As XPathNodeIterator
        XMLInfo = XMLNav.SelectChildren(XPathNodeType.Element, True)
        XMLInfo.Current.MoveToFirstChild()  Move into channel
        Do
            If (CStr(XMLInfo.Current.Name).ToUpper = "TITLE") Then
                feed.siteTitle = CStr(XMLInfo.Current.Value)
            End If

            If (CStr(XMLInfo.Current.Name).ToUpper = "LINK") Then
                feed.siteLink = CStr(XMLInfo.Current.Value)
            End If

        Loop While (XMLInfo.MoveNext())
    End Sub

This takes a XPathInterator set to the node "channel", moves into the child nodes, there there are nodes called "title", "link", "description" etc, but my method only finds title nodes, any idea why? If i print out each node it finds its just title...

Hm, looks pretty fine to me, too.

I cant see where the behaviour is caused.

Id retry it with step through debugging and thoroughly examining the variables (XMLInfo in this case). If you already did that ... :( ...
 
Found the problem, an odd one..

Loop While (XMLInfo.MoveNext())

needs to be

Loop While (XMLInfo.Current.MoveNext())

odd..
