All nine seasons of The X-Files are available on DVD. There are also four Mythology sets of 14-16 episodes that focus on different aspects of the ongoing conspiracy storylines. But chances are, you don't have time to watch all 202 episodes as a refresher before checking out The X-Files: I Want to Believe. So don't be fooled by the promises of The X-Files: Revelations, a two-disc, eight-episode set that claims to be the "essential guide to the X-Files movie."
