title: No video when using Enhanced Video Renderer
body: <p>Situation:</p>
  
  <p>Creating an decrypting filter with directshow. The graph is 
  DecryptFileSource -> GDCL Mpeg-4 Demux -> FFDShow Video Decoder -> Enhanced Video Renderer</p>
  
  <p>Issue:</p>
  
  <ul>
  <li>GraphEdit: Shows the video, <strong>works</strong> fine. </li>
  <li>GraphStudioNext: shows the
  video, <strong>works</strong> fine. </li>
  <li>GraphEditPlus: Does not show the video, <strong>does not
  work.</strong> </li>
  <li>Through Code: <strong>Does not work either</strong>. However if I replace the
  EVR with "Video Renderer" or "VMR9"</li>
  </ul>
  
  <p>Another user had this issue <a href="https://stackoverflow.com/questions/15340198/enhanced-video-rendererevr-in-filtergraph">here</a> however his answer was vague. According to Roman (In the comments on the previous link) it requires a specific initialization. However I'm unsure how to go about specifically initializing it.</p>
  
  <p>No Errors are thrown when I attempt create the graph through code. I have a seeking enabled and I can see that the IMediaPosition is working. Just no video is showing but the <strong>audio plays</strong></p>
