Audio problem: When Lister and Rimmer see Cat just after Holly explains how he evolved, Rimmer runs at Cat screaming before he passes through him and we hear a crash off screen to indicate Rimmer has just run in to something. He is a hologram and is not solid, so no sound should be heard. [The original version did not have this mistake. The sound effect was added for the now defunct Remastered series.] (00:27:10)
Audio problem: When Peter introduces the pope to his friends at work, and he is saying "Remember when we got that stripper for Charlie and it turned out to be his son?

Audio problem: 1897: Quentin challenges Barnabas by pulling a decorative sword from a wall display and pointing it at his throat. Unfortunately, the display wasn't all that well attached to the set wall. Though the camera pans away, you can hear a loud clunk as the piece falls, followed by the loud crash of shattering glass as it strikes and breaks a table lamp. You can also see the actors struggling very hard to keep straight faces as they continue with their lines.

Audio problem: When Bishop Brennan calls for the first time at the start of the episode, Ted panics and pretends to be French before hanging up the phone. You can still hear Bishop Brennan talking on the other end of the line for a few moments after Ted hangs up, which obviously shouldn't be possible.
