Try using a XmlDocument which will allow creating an XmlElement with specified name and namespace.

 string xmlpath = @"~/myxml.xml";
 string path = Server.MapPath(xmlpath);
 XmlDocument doc = new XmlDocument();

 doc.Load(path);
 var mainRoot = doc.DocumentElement; //urlset element
 var urlRoot = doc.CreateElement("url"); //create url element
 urlRoot.AppendChild(doc.CreateElement("Video:title","title")); //add element to the url element
 mainRoot.AppendChild(urlRoot); // add this new element to the main root of urlset

Example Output:

<?xml version="1.0" encoding="utf-8"?>
<urlset>
  <url>
    <Video:title xmlns:Video="title" />
  </url>
</urlset>

Or if you just want a Video node with namespace of title ...

 urlRoot.AppendChild(doc.CreateElement("Video","title"));

The output of this above:

<?xml version="1.0" encoding="utf-8"?>
<urlset>
  <url>
    <Video xmlns="title"/>
  </url>
</urlset>

Please let me know if this isn't your expected output.
