Threshold - The Complete Series, released in 2006 on DVD in North America. Only region 1 so if you live outside of North America you will need a region free DVD player to play these discs. Unfortunately this tv show has not been released in Europe. The region 1 release contains all 13 episodes, the 9 aired episodes en the 4 unaired episodes. There are no subtitles on this release. Remains one of my favorite tv shows, pitty it got cancelled so quickly.
*Update - Last year Threshold also has been released in Australia, this is region 4. Region 4 DVD's can also be played in region 2 DVD players. Unfortunately no subtitles, like the region 1 release

Threshold was a science fiction drama television series that first aired on CBS in September 2005. Produced by Brannon Braga, David S. Goyer and David Heyman, the series focuses on a secret government project investigating the first contact with an extraterrestrial species. After the success of the tv show Lost, wannabe Lost series were the new thing : Invasion; Surface; Threshold; FlashForward and of course The Event. Threshold probably had the most potential and an impressive cast. Brent Spiner [TNG], Carla Gugino [Spy Kids]; Peter Dinklage [Game of Thrones]; Robert Patrick Benedict [Supernatural]; Brian van Holt [Cougar Town] & Charles S. Dutton [Mimic, Without a Trace]. Unfortunetely the ratings dropped and Threshold was cancelled after only 9 episodes. 13 episodes were produced.
The series was first shown on Friday nights, but was moved to Tuesday in an effort to boost ratings. This plan backfired, with the show registering a sharp drop in its ratings on its first Tuesday night showing on November 22, 2005, and CBS canceled the series on November 23, 2005, with four episodes left unaired. The remaining episodes were aired on Sky1, a channel in the United Kingdom owned by Sky, who co-produced the series with CBS. The entire series was released on DVD on August 22, 2006. The series first aired on the Sci Fi Channel on Friday, October 13, 2006, at 10:00 pm, following a new episode of Battlestar Galactica.
