Death by Resurrection - S1-E12
Continuity mistake: McBride and Ryan are driving through town in heavy traffic. When the shot cuts (and their conversation continues uninterrupted), not only does the rear view mirror disappear, but an obvious rear screen projection changes their locale to a country road with trees and no traffic at all.

Continuity mistake: The panel Tony hits with a tomahawk in his quarters first appears to be molded plastic, then in a close up, appears to be painted wood, as the wood grain where the panel above is smooth.
Continuity mistake: When Starsky and Hutch are driving up to Dobey's cabin, park near the lake, and then drive into town for supplies, the car's license plate is attached to the driver's side of the front bumper as it should be, but when they're in town the plate is now attached to the passenger side of the bumper, and it's not a flipped shot. At the end, when Hutch tells Starsky he wants to leave, the license plate is back where it should be.
Continuity mistake: When the princess moves between rooms, the door in the first room is left well open, but when the shot changes to the second room, the first door is almost closed. (00:05:40)
