If you put multiple AVI or MPEG-2 files into a standard DVDA project, each file gets put into a separate titleset. Starting with DVDA 2.0, and of course in DVDA 3.0, you can set end actions for each file so that play continues with the next file.
However, there is a major "gotcha." If you press the chapter advance button on the remote of your DVD player, there is apparently no standard for what the player is supposed to do at that point, and different players react differently. At this point, I don't know whether this inconsistency is entirely due to a lack of standard in the DVD spec, or whether it is a deficiency in how DVDA creates the navigation. So, when you push the "next chapter" button on the remote, some players will go to the next titleset as if it were just another chapter, and some won't do anything, or will go back to the menu.
OK, enough preliminaries. Here's the gotcha.
On some players (like my Pioneer DV-525), pressing the next chapter button actually doesn't cause the player to read the end actions for that media. Instead, it gets it navigation from the totally obscure "object order" of the items as they appear on your main menu. This is completely and totally screwy, and sure looks and feels like a bug to me, although Sony insists that it is a function of the player. Leaving aside that whole issue, what you need to know is that, in order to get the navigation to work correctly, you must not only set the end actions (which are used to decide which media to play next when the current media finishes playing), but you must also set the object order to match these end actions so that the chapter button on the remote will actually do what you expect.
