OK, managed to extract/mount it, and it's absolutely bizarre. It's a VCD with a single very short track, but the VCD track doesn't contain the game's FMV. The game's FMV is in a normal file (as opposed to VCD tracks that are additional mode 2 tracks) called FMV.DAT in the CDI directory. What were these guys thinking?

And yes, GC/Wii/Wii U use a different format. They use a different scheme for scrambling the data, and it starts at a different offset in each sector. Then there's the unreadable sectors that get data from the BCA substituted over them.

Is it true that Xbox DVDs have the data spiral going from outside in rather than inside out?
