I am running iDVD 7.1.2 on a mac pro utilizing OS 10.6.8
I've created some video in FCP 7, a ballet in two acts. I have done all the correct steps in FCP in order to create chapter markers in each of the two acts. When I export from FCP to quicktime movie (make movie self contained) I make sure to check 'include chapter markers'. I've exported both act one and act two as separate movies in this manner. My iDVD preferences are set to 'create chapter submenus' when importing movies. Here is the issue I'm having. When I import the movie 'act one' into iDVD it creates the chapter submenus just fine. When I import the second movie 'act two', iDVD does not create chapter submenus for that movie. I am absolutely confounded. I've done a project like this in the past and and did NOT have this issue.
Does anyone have an idea on what might be happening and how to resolve this issue? I've got to get these DVD's created and burned asap. I have DVD Studio Pro but am not familiar with that software. I've always used the easy, straight forward iDVD to author DVD's.
If you are making DVDs commercially, then move to DVDSP. iDVD was a "teaser" and automates what you really need to understand. DVDSP is intuitive and gives you complete control over the authoring process. It will allow you to recognise the problem you have with this project.
I'm not experienced with iDVD (I used in for one project in 2002, and when it crashed, corrupting all the versions of my project, I never went back to it). But my guess would be that iDVD automatically creates a subchapter menu for the main feature of a disc. When you bring in the next video, it doesn't know what to do, as there's already a subchapter menu. This might be an incorrect assumption, but it is what jumped to mind when I read your post.
DVDSP is a much better application, and is the only one which allows scripting. Sadly, Adobe Encore was never completed, and doesn't do scripts. Scripts enable solutions to almost any issue of control and movement around a DVD. Your issue is easily solved with scripting.
Actually, you might be able to solve your issue with Adobe Encore. You only want buttons which target specific chapters, which is not difficult on Encore. (Encore can't turn subtitles on and off, but you didn't mention subtitles and alternate languages.)
