Create buttons: Double click on the thumbnail image in the menu item that"s located in the "Graphical View".At the top left side of the window, you will see a box titled: "Untitled Button". Making buttons work: Select a button and then head over to the "Property Inspector".Select the button, and an animated marquee will surround it. Find the Action Field and look for "Jump When Activated". Select the MPEG or marker that you want this button to activate. End actions: Go to the "Property Inspector" and head to the "General Field".Go to the "Buttons Link" field and the select the up, down, left, and right direction that you want the buttons to jump to when using the remote in the DVD player.
