title: Taglib sharp not editing rating
body: <p>I have encountered a very strange problem while using Taglib sharp. I am changes the rating of video file by using code shown below.</p>
  
  <pre><code>        TagLib.File file = TagLib.File.Create(FULLFILEPATH);
          TagLib.Tag Tag = file.GetTag(TagTypes.Id3v2);
          TagLib.Id3v2.PopularimeterFrame frame = TagLib.Id3v2.PopularimeterFrame.Get((TagLib.Id3v2.Tag)Tag, "WindowsUser", true);
          frame.Rating = 255;
          file.Save();
  </code></pre>
  
  <p>After saving file when i open the detail tab of video file from properties, rating seems not to be change. But when i again read that file programmatically in c# and check its rating value, it is 255. Why this happening and why rating value is not updating ? </p>
