title: Change the video source and displays the first frame, but i don't want this
body: <p>I have a list of the MediaElement in WPF and I have a button that allows me to change video. When I click the button, check the new video source to the video and I want to run right away, so I do video.play (). In addition, I want the video to start in a certain position and then change video.position.
  However, it happens that for a moment, it shows the first frame of the video and then the video runs at the position indicated.</p>
  
  <p>How do I prevent see the first frame?</p>
  
  <p>Thank you all!</p>
