I want to alter something on a DVD that I have and here's what happens on the DVD:

The DVD starts up with an intro video then a video main menu (all one piece), when I return to the main menu from either playing the movie or the other setup options it goes to a static main menu.

Here's what I want the DVD to do:

when I return to the main menu I want it to be the video main menu not the static main menu, but when you return to the main menu it goes to the point where the video main menu begins. I also want it the main menu to loop and not play the movie automatically after the main menu has only played once.

Can anyone help?
