DVDLab Pro, help with play all button

Hi,

I would like to know what is the easiest way to make a play all button or play scene by scene button inside dvdlab pro.

I am doing some deleted scenes, they are all in 1 movie file.

inside DVDlab pro I marked every scene with a chapter

I created a menu with buttons for each chapter.

now my question is: how do I make a button that plays just chapter 1 and return to the menu, another that plays just chapter 2 and return to the menu, etc and 1 button that's plays all.

is this can be done if all the scenes are in 1 movie file or do i have to cut the movies into little parts than create a playlist inside dvdlab pro?

if it can be done on 1 file it will be either for me than re-encoding each part alone.

thanx
