a question about DVD-lab Pro's LABtalk....

[rlowe]

I have a question about DVD lab Pro's LABtalk.

I'm a somewhat newbie to authoring. I've used Encore before but never a program as rich as DVD lab Pro.

I'm using the 30 day trial because I need to do some custom scripting. Now in looking through the "Help guide" I saw that the it can use a variance of the BASIC language through the LABtalk feature. I'd like to know several things:

1- Is it stable?
2- How complex can my programming be?
3- Will programs written with LABtalk work on a set top DVD player?
4- If Yes to 1 & 3, are there any in depth step-by-step tutorials to work with?


Let me give you an idea of what I'm trying to do.

---------------------------------------------
Imagine you work for a grocery chain and they give you a DVD with training videos.
You pop in the dvd and are presented with a the following menu which allows you to
create a playlist of only the videos that you want to see:

1- Meats
_ Beef _Pork _Chicken _None

2- Fruits
_Apples _Oranges _Pears _None

3- Vegetables
_ Tomatoes _Lettuce _ Onions _ None

-- Generate & Play videos --

In each of the section you select one subject or none
and they at the end of your selection the system will
generate a playlist that will play only the subjects you
selected.


1- Meats
X Beef _Pork _Chicken _None

2- Fruits
_Apples _Oranges _Pears XNone

3- Vegetables
_ Tomatoes XLettuce _ Onions _ None

-- Generate & Play videos --

Playlist = {Beef movie + Lettuce movie}

-----------------------------------------------------------------

Can something like this function in a regular DVD player?

If so, can someone help me out with the programming or at least point me in the right direction?

I do not know DVDLabTalk but you can do it directly by programing inner VM commands, language that runs DVD it is realy easy to make a structure, hopefully certain individual will not call me douchebag again that I'm not helping ...you can tackle it directly with VMcommands , which is the inner language of DVD

you load DVD, all GPRM (DVD's user memory locations) are zero default, you need some memory access doing this
-menu 1 is your graphical, real menu with list of items to be picked up, within menu 1, clicking on particular item will set particular GPRM to 1, and link is always looped back to the same menu.
-Button for playing videos will do one thing, it will jump into some empty (dummy) menu 2 , with only something like this :

if gprm(1) = 1 then jump to movie 1
if gprm(2) = 1 then jump to movie 2
.
.
jump to menu 1

each movie will have its gprm set to zero in pre command section and end action for each movie will have a jump back to menu 2

VM commands are difficult to learn within DVD Lab Pro somehow, that thing is not intuitive overthere. So you can just create DVD with those menus (and setting those gprm's to 1) and movies, all the jumps and you just add the rest VMcommands in PGCEDIT. That program loads VIDEO_TS. Its gui has advantage in offering you particular command, you will not make a syntax mistake and it also shows you if your command you just created is illegal. Each oject in DVD (called PGC) has pre and post command section, so you will write those codes in pre command section.

Hi guys, I'm new to this forum. Well, I'm working on a VTS menu to a submenu that is divided into cells (3 cell at least), my question is, as you would for the third infinitely cell as a LOOP will repeat without the need to use the "LOOP CELL "putting the code in the VM COMMANDS ?, would be nice to give me a reference guide. I hope you can help me and waiting for your prompt response.

Sorry my bad english XD
