How do you make chapterselection follow timeline?

[nazo-gema]

Hi Guys/Girls,

Got a Scenarist BD (HDMV) (or general) question, because i cannot figure this out.

How does one author a disc so whatever chapter you are on will be reflected in your popup/top menu, by
a dummy menu selecting automatically which chapter you are on right now?

At the moment, I have got a main menu, when you press 'chapters'
the command takes you to a dummy menu which holds the following:

This only follows which chapter you selected LAST when going back from movie to top menu. :)
(eg. when u selected chapter 3, gpr36=3 gets remembered)

Now I am trying to get this thing to follow the timeline of the video.
I know Chapters are in PSR5. I tried doing the following (in dark blue, in front of all the other if commands:
http://i226.photobucket.com/albums/dd52/mr_freakybig/menujumper2.jpg

Putting if PSR5 = immediate value for instance 3,
it would remember chapter 3?
I was dragging along the timeline, and it wasn't working at all, which means
psr5 is being reset somewhere (which I found no trace of), or I am just completely
doing it all wrong . :confused:

Does someone know how to get around this?

Thanks Much

Nazo-GEma :thanks:

UPDATE ON SITUATION:

It seems to work fine in the popup menu, and I might have found the cause of the dummy in the topmenu not doing what I want,
because of that I am now I am faced with another dilemma. :(
It seems to change PSR5 0x0000004 (say for instance chapter 4) to PSR5 0x00FFFF every time when entering the top menu when u press top menu.
So PSR5 = immediate 5 just gets overruled by ffff.
Whats this all about? That doesn't happen in the popup.

if i'm not mistaken, when 'top menu' is hit, all tracking psr's are zeroed out.

however, those pre-existing psr's are sent to psr backups (can't remember where they are, somewhere in psr35-psr40). i would use these psr backups as a way to track when in top menu.

Cool, thanks for the info dglaser6, ill have to go psr hunting now. :devil:

:thanks:

Yeah ur right, 36 to 40, 42 and 43 is backup registry.

Can I use any given one? or does it just look at one specific register?

[nazo-gema]

nevermind I found it, its psr37 :)

Thanks loads dglaser6!

glad i could help.

as similar as BD authoring is to SD authoring, it's also completely different!

Hi, everyone
So did PSR37 work? I tried it but it's not working on my current project.
