Yeah, I don't know anything about a 2CD version either. I think there was a 1.7GB avi or something, so maybe that was split to make two VCDs? Maybe Doctor M could tell us.
And if he meant 2 DVD, then maybe that would be a split version of the DVD9. There are a couple of, in my opnion, useless, torrents out there.
There's also some bizarro 1CD 910MB (which won't fit on 1CD, obviously) version of the Purist edition that negative1 made. Why, I don't know.
