Background information

• The initial US Region 1 release was issued as a transparant five-page hard plastic "booklet", with a disc mounted on each of the "pages" and came packaged within a transparant two-piece slipover plastic casing (with a disc-sized image printed on the front and the title on the spine – the art on the discs themselves was bland), mounted on a cardboard holder which had the release info printed on its back. The retailer exclusive back had the bonus DVD extra mentioned. Collected on a cardboard tray it was later reissued in December 2004 as part of the first Star Trek: Voyager - The Complete Collection, along with the other six DVD season releases.
• The Canadian Region 1 release was somewhat differently executed; it had its discs (which were art-printed) stored in standard neutral DVD sleeves, all packaged within a carton box, which otherwise featured the same (back) cover art as the US release.
• Region 2 continued for the Voyager debut season DVD releases with the packaging format as previously introduced for the Star Trek: The Next Generation and Deep Space Nine DVD season releases, and consisted of a stylized hard plastic "Special Premium Box" in which the discs, and the accompanying twelve-page foldout booklet were mounted. This packaging format was utilized for all 2003 Region 2 European and Japanese "Complete Limited Edition" (ASIN B00064191E) releases with only the accompanying booklet and the cardboard box holder backcover release information translated in the language of the target market.
• While the hard plastic box case had become the European Region 2 regular release format, it was not in Japan where it was released as a limited edition. The regular 2004 release format in Japan was very differently executed. It consisted of a carton foldout in which the discs were mounted, that came within a cardboard slip-over wrapper ("obi" in Japanese).
• As with the 2004 hard plastic box case, the 2007 Region 2 "slimline" release, consisting of four one/two-disc holding standard plastic snapcases in a hardboard slipcase, became the European 2007 reissue standard, likewise with only the booklet and DVD case inlay sleeves translated in the various languages.

  German 2009 Part 4.2 reissue with altered cover

  

  Back cover Italian Part 4.1 in translation
  Italian and German fans had been on the receiving end of market discrimination with their respective February 2008 and April 2009 reissues of the slimline variant which was split up in two releases, Parts 4.1 (ASIN B0041KWJPO, Italy/ASIN B000WEVH42, Germany) and 4.2 (ASIN B0041KXOOE, Italy/ASIN B000WEVH4C, Germany), a somewhat dubious practice exercised by the local branches of CBS Home Entertainment for almost all contemporary Star Trek series home video format releases in Italy and Germany at one time or another. Part 4.2 had its cover altered by having Seven of Nine replaced with an Alpha Hirogen hunter. Both parts came in the same slimpack packaging as the rest of the Region 2 (complete) releases.
• A complete German "slimline" variant was finally released in December 2014, over seven years after the rest of Europe had received theirs. (ASIN B00LXUGRGM) Released in November 2013, the Japanese variant had earlier already lagged six years behind the UK release. (ASIN B00F27CSWO) Italy incidentally, had to make do with imports from other European Region 2 territories.
• The 2004 Region 2 releases relied for its foldout booklet and disc cover art relied on the artwork as utilized by the Region 1 release. CBS Consumer Products however, commissioned renowned film poster artist Brian Bysouth, who had already provided the service for their preceding Deep Space Nine VHS and The Next Generation DVD UK releases, to provide similar artwork for the 2007 Region 2 "slimline" reissue artwork, which was used reciprocally for the 2017 Region 1 reissue, though in this case it had Kathryn Janeway's coiffure adapted to its later season appearances. [2]
• The 2007 UK "slimline" reissue, became the motive for Region 4 to concurrently receive its own Season 4 DVD set in the form of the near-identically executed Australasian release.
