We might also be able to force a non-conflict between 2 versions by making use of 2 different buffer overflows. That would need to be experimented with. Until then, here is a table for the versions with conflicting currentDiscBytePointer IFO offsets which we would need to be common controlled memory regions for:

Those buffer overflows are really easy to find as the IFO parsing is the first thing the DVD player does. We'll probably want to reverse engineer deeper into things like the actual video decoding, etc, in order to see if more easily exploitable bugs are available; for that, I hope others will help collaborate and share notes.
