You can clearly see the shadow of the camera as it pushes through the twin bulls head statues about 10 minutes in.
General Hammond says that the people SG-1 brought back from Chulak in "Children of the Gods (2)" identified the last four symbols that the Goa'uld used to escape. However, in that episode, the only one near the gate was Jack, and he didn't see the symbols either.
Teal'c incorrectly drew blood. He broke the seal on the vial and then inserted the needle. It should have been the other way around, yet he somehow managed to acquire a full vial.
The "C-2" label was missing on the door into the gate room in this episode.
When Teal'c and Daniel walked through the gate to get a blood sample you could still see their shadow even after they went through.
When dialing to P3X-797, they yet again used the Abydos coordinates.
Jack: By the way, how is the wound?
Jack: I understand you got stabbed in the stomach?
Sam: Oh, yeah, it was nothing. With any luck it won't even be a scar.
Jack: Good, I was concerned.
Sam: You were?
Jack: Sure, if it doesn't heal properly, you'll never wear that sweet little tanktop again.
Daniel: (about the people on the Dark Side) We came in contact with them. Isn't that special.
Fraiser: So, the question is, why haven't you and Mr. Teal'c come down with the symptoms?
Daniel: Ah, Mr. Teal'c...Teal'c's symbiote probably protects him.
Teal'c: That would be likely.
Fraiser: What about you, Dr. Jackson?
Daniel: That beats me. You're the doctor, Doctor. Ah, maybe I have a natural immunity.
Teal'c: Perhaps you will develop symptoms later.
Daniel: Thank you for the moral support.
Jack: (about Sam) No, she uh, she tried to seduce me.
Daniel: Oh, you poor man.
Teal'c: General, I would prefer to not hurt this man.
Jack: I'm a big fan of all this stuff, but art appreciation is not what this mission is about.
Sam: I was going to do my living room like this (Minoan reception hall) but it didn't go with my other stuff.
Daniel: (referring to night vision goggles) These don't look like my prescription.
Makepeace: You can count on us to watch your backside.
Daniel: Actually, I was more worried about my frontside.
Jack: Lucy! I'm home!
Teal'c: I am not Lucy
Jack: I know that. It's a reference to an old TV... never mind. Open the door.
Teal'c: I will summon the doctor.
Jack: No, come on. I'm fine. I'm back to being myself. Just open up.
Teal'c: I cannot be certain that you are back to being yourself. You referred to me as "Lucy."
Jack: Daniel, you dog! Keep this up and you'll have a girl on every planet.

The Letter Z
Just before O'Neill enters the Stargate for the first time, he swipes a "Z" in the event horizon/puddle of water with his right index finger. In the books, televisions series and movies, the letter "Z", usually cut with his sword, is Zorro's calling card.
