NBC's Enhanced Silverlight video player for the Olympics, developed by Schematic, happens to be very nice (whereas the
ordinary one is simply ordinary).
The Picture-in-Picture is cool, and allows you to keep an eye on "live" events while watching older videos. The video browser - by popularity, sport, etc - is also well done.
However, I am unable to fullscreen the video player. This rather reduces the quality of the experience for me.
I can only imagine that this limitation is built-in, as every other Silverlight video player I have ever encountered allowed easy fullscreening. Is there some reason for this?
