title: WMV media streams appear more pixelated on Windows 7 than on XP
body: <p>Our streaming media player is an in house C++/DirectShow application and runs on XP and greater.</p>
  
  <p>One of our most widely used streaming codecs is WMV, as it's widely supported.</p>
  
  <p>We've noticed that output from WMV media streams looks different on Windows 7 clients than on Windows XP.</p>
  
  <p>Windows 7 output looks much more pixelated / blocky for WMV streams.  An identical stream (coming from a media server) on Windows XP appears much smoother / less pixelated.</p>
  
  <p>The same playback graph is used on both platforms and the same media server is used to encode and stream to both clients.</p>
  
  <p>W7 client has the windows media codec that comes as part of the windows media player application.</p>
  
  <p>Has anyone else noticed this issue, or can anyone comment on what I might check / correct on the Windows 7 platform?</p>
