Aha! That actually does make sense. Is that how games are created? My daughter has several Disney (and others) DVDs that have games on them where you’re either doing a multiple choice type thing, or searching for things. I always wondered how they a) keep track of all the possible choices that each screen presents, but also b) how they keep track of what you’ve already answered that would affect a future question or part in the game. I can’t imagine that being an easy task.

For fancier games, you need an authoring package that gives you access to the system navigation commands and the GPRMs. The GPRMs can store information on lots of things, including what parts of the disc have been seen and what the score of a game is.

DVD-Lab Pro can do a lot of this kind of stuff, and multi-thousand dollar authoring packages like Sonic Scenarist can do anything you want. Encore doesn’t yet give you the ability to directly access or modify the GPRMs, SPRMs or System Navigation commands. Those parts of a DVD are accessed through Encore’s interface, which is known as an “abstraction layer”. Although Encore is a powerful program, you cannot yet do everything with Encore that you could if you were allowed to program the DVD yourself.

Keep in mind, though, that would require a knowledge of the DVD specification that is well beyond most authors. You’d also have to be a pretty competent computer programmer.

That link works in IE, though not in Firefox. They’re not sending the proper encoding from the page. 🙂
