DVD-Lab Pro Pre-Command Error

[jr43822]

I went to do a test compile of the DVD I'm creating and I got the Error/Warning about only allowed to have 128 Pre-commands and it asked if I want to continue and ignore the commands past 128. I have about 125 menus in the VTS that is giving me this trouble. You can have 250, so I'm wondering what's going on? How do I look at the Pre-commands and delete the ones I don't need?

[awlchu]

Precommands are VM associated with PGCs (a menu etc.)

128 VM commands per PGC. (pre+post+cell).

Did you program in VM with over 128 commands in any menu or bridge or movie or.....?

250? Where did you get that number?

[discman07]

Pre-Commands are navigation instructions executed before a PGC (program chain) starts. The Pre-Command Area (of each PGC) can have up to 128 'navigation instructions'-take note this is not the same as the total number of menus you have. Menu buttons can be associated with the pre-commands, so if each of your 125 menus has a fair number of buttons (and possibly other effects) you will exceed the # of allowable pre-commands.

I had exactly the same trouble with a disc I authored, however, I took the easy way out and simply deleted a few menus...(I had hundreds of menus each with 36 buttons I should also add that buttons on each menu linked to the same pgc multiple times and, I think, has a cumulative effect on the number of pre-commands associated per pgc)

If you compile sans the last pre-commands, your DVD won't work right.

You may have to rethink the structure of your DVD, good luck.

Also, try the mediachance forums-good info there too.

awlchu, 250 is the number of menus that you are allowed to make in each VTS. It's in the Help of DVD-Lab.

discman07, I have 125 menus or so that are in a random list. They each have two buttons, they all have a back button that goes to the main page of the VTS and a forward button that goes to the same movie clip. Since all these are doing the same thing, is there a way I can simplify it and use less pre-commands while keeping all my menus?

hey... trying to bump this on up, the only real info I can find is in other languages
I too have the 128 precommand limit error.....
I have many "artist videos" all with their own menus, each menu having several videos on them. -all on switched menus....
i read somewhere that I could use "dummy" menus to handle the load of my pre-commands, but I dont exactly understand how....
also, which kind of project should I have done.... noraml or advanced...

(example)
*main menu*
-play all
-artists
------Artist #1
--------(Has About 10 Videos and Links to another menu with more of this artist's videos)
-----Artist #2
-subtitles

- this kind of set up all on switched menus.... I am a newbie, and thought I finally had the hang of this until compiling..... please help
if you new me to post my report.. let me know

Not sure if any of this will help or not...

You can use dummy clips -- something like a second of black, with an end action of going wherever you want -- normally this clip will cause a new PGC to be created. More tricks might be available after layout created using something like Pgcedit I think to maybe shorten playback.

Dummy menus work the same basic way to my knowledge, auto activating to go somewhere else, but not sure that would help. The Pro version of DVD Lab allows more then one VTS -- is that an option?

thanks for the quick reply....
I do have more than one VTS, but I am still having the 128 pre-commands limit error

I don't know the VM command engine/syntax in DVDLab. But with dvdauthor it is 'common' to use a second pgc (just for the commands) if more than ~100 commands are necessary.
Assumption: GPRM1 is the variable to evaluate
Pseudocode:
[pgc1]
if (GPRM1>50) jump next pgc
if (GPRM1=1) do something
if (GPRM1=2) do something else
...

[pgc2]
if (GPRM1=51) do something
if (GPRM1=52) do something else
...

Have you searched or asked at the mediachance forums ? If not, why not ?
