There's some ogg yes, but its not all ogg.

The minizip files are compressed with deflate but there's something else funky going on...

There's also some encryped Deflate Steams that have TransformIT encryption layered above. It's been a while since I've been on the scene so I don't know if I can actually be interested to look into this further or not, but I'll link some useful tools here:

EDIT 1 / ???: Maybe you could hack together the minizip extractor to just write the raw deflate streams, concatenate them (which should allow xtool to process them correctly). Then, just xdelta your hacked together file back to the original minizip.
