Scripting Overview
Scripts you add to your project contain commands that allow you to access the
functionality available in all DVD players. Each script can contain up to 124 commands.
Every DVD player contains a micro-controller that can execute a set of commands defined
by the DVD-Video specification.
The commands defined in the DVD-Video specification are at the level of microprocessor
machine code, with very simple commands used to initiate desired functions. You may
find that some of the concepts and terms are a challenge. Therefore, when learning
scripting, proceed with initial deliberateness and caution—it is very easy to author titles
with scripts that just don’t work. You should also use the Simulator and test builds of
your project using the Apple DVD Player to verify that your title plays back exactly as
intended.
