Hi guys!
I'm using DVDSP and with excellent help from Ian, I now have some additional questions I hope you can help me with.
I have a Track with some Chapter markers in it.
Now I want to add buttons over video, using a subtitle graphic.
Using an STL file, I add a subtitle every 2 seconds throughout the Track.
(Not sure why I can't use one single subtitle here..)
When adding the titles, I make sure the in- and outtimes matches the Chapter markers.
Then I add my 5 buttons, setting audio stream 1-5 for each button.
What is the next step? I guess I must use DVDAE to add the buttons for every one of the 2 seconds subtitle clip?
Clarifications

The reason to have multiple subtitles is so that the button info "refreshes" regularly. This gets around the "one-activation-only" issue you have found using DVDSP alone.
So, whereas with DVDSP each button can only activate once, if you make subtitles and convert them to buttons in DVDAfterEdit ( not DVDSP ) you can avoid the problems you have with hardware players. ( It may be necessary to have the subtitles closer together, by the way - one second or less. ) As soon as you tick the "Button marker" box in DVDSP, it merges all the subtitles into single button highlights, so there's no point in using an STL script.

No, I'm afraid you haven't grasped the concept yet.
Briefly, using DVDAE you need TWO DVDSP projects - one with short subtitles but no buttons and another one ( the "Template" ) with buttons set up as you currently have them. You then copy and paste the button info FROM the "template" TO the version with all the subtitles. DVDAfterEdit won't merge the subpictures as DVDSP does, so your buttons will work as intended, but refresh whenever a new subpicture is encountered. I hope this is clearer ? Hopefully if you re-read Uli's article and the email I sent where I outlined the method, it will make sense. The big advantage is you only set the buttons up once - in the "template" project. You can then copy and paste them to a whole track in DVDAE in one go, to all the 2-second subpictures in one go.

This is a similar but related issue. DVDSP makes each new button re-initialise, which is what is happening when you jump to a new chapter. This setting can be over-ridden in DVDAfterEdit. But in your case, you eventually want buttons-over-video to jump to the next chapter. This will require you to jump to a script ( "dummy PGC", in DVDAE terminology ) containing code to check which chapter is playing and go to the next one. At the same time you can store the current button number and make sure it's passed on to the next chapter point correctly.

Adding buttons over video
I should say, that using only DVDSP I can get this to work in software players such as WinDVD and PowerDVD (and Apple DVD player).
The main use (if not only) will be on PC, not stand-alone DVD.
Another follow-up question:
WHen I jump to the next chapter, the audio remains at current stream (very good), but it's always button #1 that's highlighted. Why is this? The user might be confused, since the current stream is (still) 4, but button 1 is highlighted.
