Continuity mistake: At the start of the episode Kryten has crashed Starbug 1 onto the psi-moon. Lister and the Cat rescue him in Starbug 2, yet when the crew search for Rimmer in the swamp, they are in Starbug 1. (00:06:10 - 00:19:45)
Terrorform - S5-E3
Continuity mistake: Just after one of the hooded legions reads from the scroll, he manages to turn around and face the opposite direction in one camera cut. (00:10:45)

Terrorform - S5-E3
Continuity mistake: When Lister, the Cat and Kryten figure out how to escape, Kryten says 'precisely' and raises his right hand. In the next shot, both of his hands are raised. (00:22:15)
Terrorform - S5-E3
Visible crew/equipment: When Lister, Cat and Kryten leave the cockpit with the plan to make Rimmer feel good about himself to escape, a boom mic can be seen in the top left corner of the screen. (00:22:45)
Quarantine - S5-E4
Visible crew/equipment: When Rimmer asks the crew if they had forgotten Red Dwarf could only sustain one hologram, it shows a shot of the rest of the crew who say nothing. At the top of the screen, a boom mic can be seen. (00:03:00)
Quarantine - S5-E4
Visible crew/equipment: When Lister wipes down the biohazard cabinet, a boom mic can be seen in the top right of the screen. Also, just before the camera moves past the pillar, the entire microphone and arm can be glimpsed. (00:05:00)

Continuity mistake: Just before Dr. Lanstrom appears, Kryten is standing behind Lister. In the next shot, he has moved much further away from him, then moves back and forth between shots. (00:06:40)

Quarantine - S5-E4
Revealing mistake: As pointed out by Danny John Jules on the DVD Commentary, during the 'Feckles, Heckles, Hackles, Schmeckles' argument, Cat pushes his face right against Kryten's, leaving a brown makeup smear on Kryten's forehead. The mark is gone in the next shot. (00:19:45)
Quarantine - S5-E4
Audio problem: When Rimmer is talking to Lister, Cat and Kryten in the dress, the Cat says "We thought you'd gone nuts" and the shot cuts to Rimmer where the Cat then says "We were trying to heal you." When the shot is on Rimmer, the Cat's reflection can be seen in the mirror and his mouth doesn't move with the line. (00:21:05)
Quarantine - S5-E4
Continuity mistake: When Rimmer is looking at the crew through the viewscreen in Quarantine, the reflection of the crew in the glass changes between shots. (00:21:20)
