It strikes me that Adobe can't settle on what to call an Encore project that has been output to Flash.
Is it a "Web DVD"? That term is used repeatedly in the New Features section. Is it simply "Flash". The Build panel lists the format as "Flash" and the Output as "Flash (.swf)." Or is it a "Flash DVD" or a "Flash Project"? Both terms are used in this page.
Flash output is an important feature of Encore. It would be a good thing to use a consistent name for the assets you end up with after you output to Flash.
