    ?>
    It:
    • Provides a box to enter a video URL
    • High quality MP4 is default, low quality FLV is optional
    • Renaming the video to the title is optional, but activating it means the data has to travel through the server - slower and more expensive, but hey it's a feature baby.

      I've got a class that can retrieve youtube files based on the identifier. You will have to integrate it into an app yourself though.
      Perfection comes at a cost



      I accept liberty!
