The documentary on the making of episode 6 (season 2) is also worth watching where they show how they made the mission impossible type scenes.
The season 2 DVD's are not edited like the original season 1 disks (which has now been sorted).
A note about the edited Season 1 disks: If your season one box states 52mins per episode on the back, then you have the edited version. The box should say 59 mins per episode (unedited version)
