The easiest way to accomplish that is create a track with that intro video, and set the “first play” to that track, and the “end jump” of the track to the menu.
The “First Play” can be enabled in a number of ways, but if you go way to the left, in Graphical View (it should have two tabs–Graphical and Outline), and once you’ve created a track, Control-click the icon for that track, and click on First Play. You’ll see a little DVD/Play icon supered over the icon for the track when it’s set to First Play.
For the “End Jump” of the track, make sure the track is selected (click on an empty spot in the timeline), and go to the Inspector (usually bottom right corner). You should see the track’s name at the top, and “End Jump.” In the drop-down for End Jump, select the menu, or even specific buttons on the menu to start on. If you want, you can disable remote controls by going into the Inspector again, under User Operations. Here, when an option is checked, it’s disabled (not enabled). You can choose what to disable.
Hope this helps,
