When Gabrielle uses her staff to pole vault over the cart of logs, the staff actually disappears at the apex of the jump as she passes over, reappearing in her hand when she lands.
When Gabrielle is playing her pan flute her lips move randomly along the reeds and have no correlation with the actual notes being "played," clearly indicating the music was dubbed in later.
At about three minutes in, Gabrielle wisely drops to the ground to let the cart pass over her. Xena runs over to her, lifts her to her feet, and yells for her to drop to the ground where Gabrielle was before Xena dragged her up right.
