Factual error: In the whole episode, Romania is depicted as a monarchy with the king in a position that allows him to make political decisions. However, Romania ceased to be a monarchy in 1947. By the time depicted in the episode (circa 1997), Romania was a republic and its head of state was the president. Members of the ex-royal family did not hold any positions in the Romanian government and were certainly not authorized to represent Romania in international events.
Factual error: Aphrodite's son and Psyche's husband is Eros, not Cupid. Venus's son is Cupid. (Eros is Greek and Cupid is Roman).

Factual error: To protect the warp core, Janeway instructs Paris to move away from the rings at Warp 7. Moments later (Janeway, Torres and Tuvok are still in the same position), Paris tells Janeway they are 0.6 light years away from the rings. Warp 7 is 656 times the speed of light. It would take about 8 hours to travel 0.6 light years at Warp 7.
Suggested correction: The warp scale, especially since it's fictional, has never been precisely defined.
While it's never been defined, certain aspects of warp speed drive and the length of a light year are accepted. Even if Warp 7 is double what is suggested in the mistake, it would still be 4 hours. The scene in question shows no lengthy travel at Warp 7.
Factual error: During Lizzie's visit to Rosings Park, Lady Catherine presses her to stay longer, saying that if she will stay another month, she will be able to accommodate Lizzie "on the barouche-box" as far as London. This is nonsensical. What Austen actually wrote (Ch. 37) was: "And if you will stay another month complete, it will be in my power to take one of you as far as London, for I am going there early in June for a week; and as Dawson does not object to the barouche-box, there will be very good room for one of you. . ." The box is the coachman's seat on top of the carriage. Dawson is a servant, but if there were enough room inside the carriage, she would ride inside. What Lady Catherine is doing is offering Dawson's inside place to Lizzie. But in the movie, she is offering to let Lizzie ride outside next to the coachman. Not much of a treat.
