When adding chapters to a movie to burn to a DVD, do you do it in FCP or DVD Studio?

Any instruction will help also. (I can't find either of my manuals.)

I add the chapter in Final Cut, just hit "m" to make a marker and then m again to open the marker option box and press the chapter button. When you export make sure to check the include markers check box in the export window.

Dont forget if you lose your manuals they have them in pdf form when you open up the help menu......either way works but i think nate's way is a very solid way to do it.

Thanks guys! I forgot about the PDF's!
