title: Get VideoEntry by video id
body: <p>I use Gdata for uploading my video on youtube. After uploading, I save video id and I want use this ID in future for retriving some information about my video (status, for example).</p>
  
  <p>But how do this right? I have video id like - "tag:youtube.com,2008:video:VKm6-1jUgGc". I guess, real id is - VKm6-1jUgGc. But when I try do this:</p>
  
  <pre><code>createdEntry.getId(); //there I get video ID
  
  videoEntry = service.getEntry(new URL("https://gdata.youtube.com/feeds/api/users/default/uploads/videoid?v=" + "VKf6-1jUgOc"), VideoEntry.class);
  </code></pre>
  
  <p>I get error, that video id is incorrect!</p>
  
  <p>Then, I try to use this:</p>
  
  <pre><code>createdEntry.getMediaGroup().getVideoId();
  </code></pre>
  
  <p>But this don't work too.</p>
