title: youtube API: Get mosts popular video uploaded by a user
body: <p>Here is the original URL to get the xml awnser:
  <a href="http://gdata.youtube.com/feeds/api/users/RIPPERvideos/uploads" rel="nofollow">http://gdata.youtube.com/feeds/api/users/RIPPERvideos/uploads</a></p>
  
  <p>I would like to get all the videos uploaded by this specific user (not be limitted to 20). Also I would like the data to be sorted. </p>
  
  <p>I tried these params:
  <a href="http://gdata.youtube.com/feeds/api/users/RIPPERvideos/uploads?orderby?v=viewCount" rel="nofollow">http://gdata.youtube.com/feeds/api/users/RIPPERvideos/uploads?orderby?v=viewCount</a></p>
  
  <p>It only seems to be working for these kind of request:
  gdata.youtube.com/feeds/api/videos?
      q=football+-soccer
      &amp;orderby=published
      &amp;start-index=11
      &amp;max-results=10
      &amp;v=2</p>
  
  <p>Can someone help or guide me?</p>
  
  <p>thanks</p>
