GPRM Based Button feature
by Pierre-Luc on Jan 15, 2007 at 6:08:47 pm

It seems that DSP4 has not been improved, isn't ? My script won't work with it checked. Simple as set any GPRM with the SPRM8 value, then linking to the movie and jumping back with a script that jumps to the menu with GPRM Based button checked. Anyone else's experience ?

I've used this script many times and it works fine. Could you post your script so we can see?

Here's the example:

Warning->Logo->Transition->Language Menu->

English Menu
Pre-Script:
mov Subtitles, 0
mov Play All, 0

All buttons link to the same transition before going to the specific movie.

This transition (As a menu) has a Pre-Script:
mov Button, SPRM 8
div Button, 1024

And the Timeout Target is this script:
mov Subtitles, 0
mov Play All, 1 if (Button = 9)
Jump Track 1 if (Button = 1)
Jump Track 2 if (Button = 2)
etc.

The End jumpt for each track is:
Goto 3 if (Lang = 0)
Gto 5 if (Lang = 1)
Jump Menu 1 (Button) if (Subtitles 0)
Jump Menu 2 (Button) if (Subtitles 1)
Jump Menu 3 (Button) if (Subtitles 0)
Jump Menu 4 (Button) if (Subtitles 1)

So... I thought that because my GPRM "Button" was divided by 1024, but even using the right value, say 3072, it returns to the first button.

It could be the Pre-script. Set your GPRM via SPRM 8 in the Timeout script instead and see if that works.

mov Button, SPRM 8
div Button, 1024
mov Subtitles, 0
mov Play All, 1 if (Button = 9)
Jump Track 1 if (Button = 1)
Jump Track 2 if (Button = 2)

Right, but my transitions are placed within menus, if I set my GPRM within the Timeout, I'll the SPRM8 (1024) of this menu. I could use track for transitions, but it slows down the navigation...

I don,t understand, because I look at my GPRM and it retains the SPRM8 value, it needs it to link to the right movie and it works. The simulator works with these scripts, but not the Apple DVD Player.

But your "Menu" transition has no buttons so it will remember the last button chosen on the intial menu.

No, it gives you 1024, even w/o buttons. Just made the test, and it won't link to the right movie.

Here are a couple of thoughts

1) make the transition a video track instead of a menu

2) jump to a script that sets the GPRM to the button value then jump to the transition which end jumps to your script that jump to the correct movie

Found it on Apple Discussion board. When using GPRM Based Button, you can't use Pre-Script on the samed menu, which you target the button.

Thanks eric.

Gald you discovered the issue. :) I didn't know DVDSP defaults to button 1 even in a menu with no buttons. Is there a way around this in the inspector? Isn't there a default button setting?

I think its part of DVD Spec. There is a Default Button setting, but you don't set any if you want to control which is selected.

It also doesn't work if you check Start at Loop Point, because this function acts like a Pre-Script. So funny Apple... God bless DVDAfterEdit!!
