DVD main menu

Hi everyone,

I am embarking on a project for a client. It is a product video that has three elements based on art projects. He basically wants the dvd to be interactive with a video intro then have the three choices of portraint, landscape, and still life. I was wondering if you can use a video file as the main menu, then set up submenus with chapter markers and stories, because at the end of each of the three segments he wants basically 40 mins of ambient music and pictures of artwork. My main concern is if you can have a main menu that is actually video with buttons that appear at the end of the intro video instead of it being a still picture, is it possible. I will be using DVD studio pro.
