Visible crew/equipment: Matthew is talking to Hank in the saloon about Hank's horse that Brian wants. After Hank agrees to let Brian work for him to pay for the horse, Matthew walks out of the saloon. The camera pans to the left slightly and a microphone can be seen moving behind Hanks head. (00:32:30)
Continuity mistake: Near the beginning when Colleen and Becky are talking to the boy, there is a boy walking in the background. When he loses his hat, he is behind the boy talking to the girls. In the next shot he is already behind the two girls, which is quite a great distance to cover in a split-second. (00:06:30)
Audio problem: Just before Dorothy has her operation, Mike is seated at her desk looking through her medical books. Sully pays a visit to comfort her. During their moment, you can hear slight foot shuffling from the camera crew in the foreground - which is not coming from the outside. Also, you hear a slight grunting during a pause in their conversation.
Visible crew/equipment: Loren wakes Dorothy in the middle of the night to mention selling the store and taking her on a trip to New York. While seated at her bedside, you can see shadows of a crew member on the bed pillows next to her, and hear some muffled foot movement while Loren is seated, talking to her.
Continuity mistake: When the whole town comes to support Matthew, we can see Hank and the reverend walking up behind him. A few seconds later, we see them both again, now they're walking with Colleen and Brian, and they have just come around the corner to see what all the fuss is about.
Factual error: When the woman is giving birth and Dr. Quinn has to perform a c-section, she gives the baby to Mrs. Cooper, and after about a minute, she gives the baby to the mother. Dr. Quinn then leans towards Mrs. Cooper and they smile happily; she doesn't attempt to continue the "surgery". Even nowadays doctors need several minutes to close up again after a c-section, so there is no way that Dr. Quinn was anywhere near finished. Leaving the patient cut open on the bed is pretty irresponsible, something she would never do as she has to prove that she is a good M.D. (00:30:00)
Visible crew/equipment: When Dr. Mike tells Jake that he's not ready to go home, a black chalk T-mark is visible on the floor near the door. Then as Jake pounds on the door he tells her he has a business to run, and the moving boom pole casts a shadow on the wall, at the top, right side of the screen. (00:26:35)
Visible crew/equipment: The morning after Dr. Mike and Sully spend the night with the Cheyenne, when Wolf finds a ripped piece of Brian's shirt Sully tells the wolf to find him, and three shots later just as the camera pans toward the right, in this wideshot a crew member (presumably the animal trainer) who is standing on the hill ducks behind the bushes, near the top center of the screen. (01:05:30)
Continuity mistake: Jesse and Brian enter the President's office from The Secret passage shortly after Sen. Steward and Capt. Burgoyne leave. When the two boys hear the door rattle, Jesse whispers to Brian that somebody's coming and they race off Right. The President's desk is still in 3/4 view, and remains so as Burgoyne re-enters and goes to the desk, noticing the open cabinet door, which he checks. He hears movement and voices a threat, then goes to check the curtains only to find nothing. The camera then pans down to show Jesse and Brian hiding scared under the desk. Given the brief timespan, the two boys could not possibly have moved there without Burgyone noticing their presence.
