We received an engineering sample of the Pioneer DVR-A04. The retail version of the drive will come under the codename "DVR-A04". The OEM model will be named "DVR-104". The retail box will included: The drive itself, multilingual operating instructions (7 languages), 5 pieces of Pioneer 74min CD-R media, 2 pieces of Pioneer 4.7GB DVD-R "General use" media, mounting screws, configuration pin jumper, forced eject key and a Staedler Lumocolor pen.
