Does anyone know what software was used for making early DVD Videos?
Given that this is software related (I mean, a computer had to be involved in the development of DVDs, they wouldn't be digital if this wasn't the case), I figured it would be worth posting about here. If this isn't appropriate for this forum, then I apologize.
Nowadays we have programs such as Nero, iDVD, or Windows DVD Maker for making our own DVD Video discs, but given that programs like those weren't around until the 2000s and DVDs were introduced to the world in 1995-97, the question that has been crossing my mind for years is what software (if any) was involved in the development/creation of the early studio DVD Video titles?
One theoretical guess is maybe special software was in use that we (the general public) don't know about, like maybe some early DVD authoring program. Another theory is that maybe the menus and such were programed manually with some sort of programming language (IDK what was used for DVD Menus). If anyone here has experience in this field of technology, feel free to tell me what you know about this.
