Easily done. You have A, B, C. Put a new instance of A in your submenu and put new instances of B & C in the main project folder (not on any menus). Give the new instance of A en end action to play B, give B an end action to play C, then give C and end action to return to whatever menu you wish.
DVDA2 will only use each one time, no matter how many instances/pieces you use.
(If you're using DVDA1, you won't be able to do this).
This sounds good - will doing this have any effect on playing the single movies from the main menu, or are the end actions defined differently from each menu?
End actions are defined for each instance of the media, NOT the menu. This is one of the key things to learn about how DVDA works. Thus, if you want to have the ability to have one button that plays all the media uninterrupted, and another button that returns to a menu after each media (MPEG-2/AC-3) plays, then you have to drop each media on the timeline twice. Rename them immediately after dropping them on the timeline so you can keep track of what you are doing. Set one menu to point to the first instance of the media, and set another menu to point to the other instance. Set the end actions for the first instance to point back to the last menu. Set the end actions for the second instance to point to the next media you want to play, and set the end action for the last media in this set to go back to the last menu.
This only works in DVDA 2.x because this version only puts one actual copy of each media onto the DVD, no matter how many instances of this media you actually drop into the project.
For Chapters in a Scene Selection - if a return to menu is required before running into the following chapter, does this routine need to be applied, or can the "end flag" in the timeline be dragged as in DVDA1 ?
