That's the format not considered good enough. Even in Aaron's own words (paraphrasing) he said his format was not perfect but better than nothing, and at least we'd have something and not just let the discs rot away. I think it also needed a very specific setup and I don't remember if the method is even public or not. But we're probably going to have to go back to it and admit he was right all along and stop chasing the perfection dragon.
