FCBN-0001 is actually FCBN-0002 (regular edition) plus FCBN-0001A, which is a bonus disc included only with the first pressing. FCBN-0001A is listed separately.
The full-cast audio commentary is cool! I think it's as interesting as the show itself. Your mileage may vary, of course.
This disc has an automatic random start-up message selection feature. When you pop in the disc and start playing it, it will play one of N start-up messages. I have no idea how many different ones there are.
One of the promotion video may contain some new footage, but I'm not sure and I don't really care. As far as I'm concerned, there are no new footages in this DVD, so there's no reason for me to do screen captures. Instead, I'm listing a photo of the DVD cases.
