Fox Home Entertainment re-released every season of The X-Files on Region 1 DVD in 2006 in slimmer packaging. However, some discs were omitted therefore some special features listed above may not be present on the newer Region 1 Sets. Fox Home Entertainment also re-released the The X-Files on Region 2 DVD in slimmer packaging in late 2004/early 2005, the content was exactly the same as the original releases.
This is the only season box set to have a 18 certificate in the UK, due to the exorcism theme of the episode "The Căluşari", as the first season box set and the following box sets from the third season onwards have a 15 certificate.
