In fairness, if I were an industry cabal trying to hold a monopoly over a ubiquitous format, and had my IP encryption cracked within an hour of releasing it, I wouldn't want electronic copies of my IP floating around where they can be easily copied and leaked.

Anyhow, it seems that the answer to my first question is "Yes, there are gaps in our understanding of the DVD video format." I'm picking through the libdvdread source code, and there are lots of "unknown" plug parameters.

So that leads to question 2: do we know anyone in Tokyo who wants to spend a few afternoons in the National Diet Library reading over the spec to fill those gaps? I'm guessing that digitising  the standard is out of the question, since it would have been done already and is probably still under copyright/patent.
