Yes…integration between Encore and Photoshop is much better.
David was referring how the DVD spec handles layered menus in both DVDSP and Encore. Each layer or state is really a separate menu within a single Program Chain. Thats why you get that clunky & slow navigation. There used to be time where they crashed players and is a reason you dont see layered menus used that much.
The results are the same but yes, integration is easier and faster in Encore.
