Total menu size exceeds limit?

I finally put my video together in Premier and output it as an mpg2 dvd video. According to Encore, the file is 3.77 GB. What I don't understand is, the check project window says, "total menu size exceeds limit". I only have one menu button that says, play, so it can't be the menu can it? What I've read is that the multiplex setting is duplicating the audio file maybe? I'm not sure what that means, I only know, the file should be small enuf to fit on a 4.3 Gig DVD. What can I do to get this blasted DVD finished? I"m working in CS 4. thanks
