YouTube is running Microsoft Silverlight in CBS’s dedicated channel for March Madness. In the CBS YouTube Channel located here: http://www.youtube.com/marchmadness there’s an embedded Sliverlight player which appears to be just the same as the one running on the free March Madness on Demand site.
This is really amazing that Microsoft video site that msn video is not using Silverlight technology but Google is able to use Silverlight technology in YouTube
