title: Custom post type archive, more pages don't work
body: <p>I have a site on which a lot of video's will be posted next week. The videos are posted with a custom post type, with just  'to', 'from' and yt video id. I wan to load a lot the videos on an archieve page, but not more than x per page. So x posts on page 1, x on page 2 and so on. Unfortunately, the page number doesn't show up, the 'p' container just stays empty. Here is my code:</p>
  
  <pre><code>      $args = array( 'post_type' =&gt; 'video'/*, 'posts_per_page' =&gt; 3 */);
          $loop = new WP_Query( $args );
          if (have_posts()) : 
      while ( $loop-&gt;have_posts()) : $loop-&gt;the_post(); 
  
  
                  &lt;?php endwhile; ?&gt;
                  &lt;p&gt;&lt;?php posts_nav_link('&amp;#8734;','&amp;laquo;&amp;laquo; View newer posts','View older posts &amp;raquo;&amp;raquo;'); ?&gt;&lt;/p&gt;
                  &lt;?php endif; ?&gt;
  </code></pre>
  
  <p>I have emptied the part between the while, because in that part I only call to basic functions like the_permalink and the_content.</p>
