In fact there is precisely one extra: the spectacularly misnamed The Making of the Record of Lodoss War.
When I look at a "making of" I expect behind the scenes interviews, a look at the production process, alternative character designs, storyboards, etc.
In other words, something that more or less resembles a tour of the the production facility and process.
The Making of the Record of Lodoss War is none of these things, and I would bet that it never came within miles of the production studio.
It is instead a short promotional puff piece filmed at an science fiction convention where the first episode was previewed.
From the on stage interviews I get the impression that only three, maybe four, episodes had been completed at this point.
The main thing I take from this piece is that completion of the series was never a done deal, and that the producers were desperate to leverage the popularity of the original novels to boost the sales.
The whole event reinforces my belief that the pilot episode was deliberately made out of sequence to hook the audience and generate momentum. Some of the on stage comments hint at this fairly strongly.
Short enough to be amusing, shades of Otaku no Video in content, a world away from truth in labelling.
