I just pushed this out today so please be the first to come and play with it.   MSDN will be rolling out a new Silverlight player which embeds in the page and supports full-screen.  We’ve re-encoded the videos that needed it and it’s ready to go.  You can click on either video on the VB developer homepage or go directly to the VB How Do I Videos page and check out the featured vids or select from any of the videos Beth Massi has produced!
