Creating a Silverlight 1.0 video player using Expression encoder is incredibly easy ( 3 clicks and done).. Debugging it or tweaking it was not as easy... Until now..
Jim Thill posted the debug ( read:uncrunched, unoptimized ) version of the media encoder templates.. so now you can read and tweak the code.. It also comes with a document on how to document the player skins..
The template & docs are here. Enjoy!
