When Anakin is with his friend talking to Padme in the podracer hangar, when you see the shot of Anakin and his friend, in the background, you can see Qui Gon walk into the shot from the right. The camera switches to Padme and back to Anakin and Qui Gon enters the shot from the right again. No, you didn't hit the rewind button on your remote on accident, you witnessed something that George Lucas didn't.
