When SG-1 exits the Stargate on the prison camp planet, all of the Jaffa guarding the gate are supposed to be unconscious, yet you can clearly see one of them moving his head and foot before SG-1 move along.
When the Stargate is being dialed up at the start of the episode, the final symbol that is locked in as the point of origin is the symbol that represents earth, when it should be the one of the planet they are arriving home from.
