Corrected entry: The crew members are in a forest having hallucinations because of the wraith machine. Sheppard is hallucinating that he is in the desert during the war helping an injured soldier, so when he's walking around why isn't he bumping into trees? He sees nothing but sand, even mentions it at one point, but they are in the forest and he walks around pretty freely.
Corrected entry: When Dr. Weir is distracting the scientist by talking about World of Warcraft, he says that he has a level 75 character. The maximum character level is 60 at the moment, and 70 with the forthcoming expansion pack. Not a character mistake, as he clearly knows enough about The Game.
Correction: Who's to say the WoW game in the Stargate universe operates exactly as ours? Their base game, or the newest expansion could allow up to level 75 characters.
Corrected entry: After Rod has been sent back to his original universe, the team checks how much power of the ZPM they have wasted. The monitor reads "ZPM Module Depleted". This makes no sense, since ZPM is an abbreviation for Zero Point Module. Therefore the monitor should read "ZPM depleted" and not "Zero Point Module Module depleted".
Correction: Can't really call that an error. People talk about their PIN number all the time for example. Your Personal Identification Number number? At worst it's an error on the part of the person who programmed the Ancient/Terran interface program, but not even significant enough to count as a character mistake.
Corrected entry: When the drones are chasing the jumper, it goes under water to avoid them and the drones do not follow it. However, Beckett uses the same drones later to destroy an underwater target.
Correction: This is explained within the DVD episode commentary by Martin Gero and Paul Mullie. There was initially a scene showing that the replecators thought that the puddle jumper had crashed so the drones were withcalled. This had to be cut due to time.
Correction: The human brain has more than one set of visual "control" systems which creates a phenomenon called "blindsight" when the higher visual functions are either disrupted or-theoretically-affected by some sort of illusion. Basically, blindsight is involved in "instinctual" responses to visual stimuli-like avoiding collisions or aligning the fingers to grasp an object-which can function even as the person can't consciously register anything visually.
