Both volumes were released on VHS in North America, (only the first episode was included on the DVD release however), and only the first episode was dubbed into English as the others were left in their original Japanese audio with English subtitles.
Dragon Knight 2, the second episode which was released by ADV Films on VHS, is not included on the DVD release. The second episode was created by Five Ways and is considered closer to hentai over the ecchi-filled first episode. The reason for non-inclusion is that licenses won't allow competing companies' shows on the same disc.
