I got the DVD from the library. The library sticker says that is it Volume 9. But get this.... the actual disc also says it is Volume 9 and lists the Volume 9 episodes - engraved right on the DVD disc. When you play the disc, it has the volume 1 episodes on it. The library has no explanation for this, and I didn't expect them to. Is it simply a manufacturer error, and have you ever heard of something like this occurring before? Maybe they did it on purpose to make you believe you are in the TWILIGHT ZONE?
