Avenger 2.0 - S7-E9
Corrected entry: Right after Jack reports that the gate is down and Carter and Felger are talking about...something...you can still see Jack in the screen in the background. He actually moves closer to the MALP camera twice. As the camera angle changes, you see him do it again.
Correction: Not a mistake. Scheduled transmissions were possible FROM Earth's Stargate - no reason why Jack would've cut off. His moving closer to the camera was a comic moment.
You're missing the point of the mistake. Continuity mistakes occur when the camera angle change and no time elapses. The mistake is saying Jack moves closer to the MALP's camera and then does it again in the next shot (with no time for him to move back to repeat the action).
