Other mistake: Duke is checking old copies of the Haven Herald around the time of Lucy (27 years ago). A headline on the one he's reading is about Lucy's disappearance. A moment later, he's reading a story about a meteor shower that occurs every 27 years; but the text we can see states that it just happened, and refers to dates in 2010 (having just happened, not '27 years from now'). This paper is supposed to be a 1983 edition. Also there is fake Latin 'filler text' printed in some columns.
Suggested correction: Lucy's disappearance is at the top of the newspaper and the hunter storm is at the bottom of the same page. Also, the paper predicts the next storm to occur. Just like how we know when to expect the next lunar eclipse or the next meteor shower, so I don't see how this is a mistake.
It's not a prediction of events to come, it's an article telling about the recent event, which states it was seen on the morning of the October 21, 2010. It even compares the 2010 shower to a previous shower that occurred in 2009. The mistake is valid.

Other mistake: The King's ship has no steering devices, steering wheel/pin, no steerman, and no crew. (00:26:00)

Other mistake: The recap of Episode 4.1 has a scene that hasn't been shown until episode 4.2 or 4.3 where the FBI neighbor gets hold of Jennings in his garage to confront him on his alleged affair with his wife. The similar issue with another episode is seen in episode 3.12 or 3.13. (01:00:00)

The Ones You Can't See - S3-E7
Other mistake: Before the Seals went on their counter-sniper operation they were briefed that the enemy snipers were going to be using SVD-63 Dragunov's which have a range of 800m. The two enemy snipers who were killed never had Dragunov's, they had standard bolt action type rifles without suppressors, hard to identify a specific brand. They engaged the Seals from a distance with unsuppressed weapons over a crowd of people and the crowd didn't hear a thing. This is a falsity, a 7.62mm shot can be heard for 3km. (00:37:26 - 00:38:00)

Other mistake: At the start when the Lexus is found it is shown as a mirror image as can be seen by the badge and registration number. (00:03:57)

Other mistake: Throughout season 1: The emergency workers are sometimes seen wearing a black jacket with an English spelling mistake on it. It reads "FIRE EMS RESOUE." Obviously the last word should be "RESCUE."

Other mistake: As corvette guy races to get away from Ponch, the steering wheel breaks away, coming loose in his grip. Yet the car magically veers a sharp left before halting to a stop, instead crashing into the trees straight ahead of him.

Other mistake: Given that Alice only stole some of Dana's ashes to scatter at the camp ground, the amount of ashes seen poured into the waterfall by all of the characters is totally unrealistic; much more, in fact, than what would equate to an entire cremated corpse.

Other mistake: At the end, when the reflection of burned Lucy still shows her beautiful, Dracula's reflection shows him as he is seen; not old and ugly as in his usual mirror reflections.

Did the Earth Move For You? - S2-E1
Other mistake: Viv and Phil are waiting in his office for the power to come back on after the earthquake, but you can see lights on in the building across the street. (00:16:30)

The King of the Delta Blues - S2-E6
Other mistake: We see a character get shot and falling forward with back arched, as if the shot came from behind. Moments later we see the shooter and the shot came from the front. (00:31:25)

Remembrance - S1-E1
Other mistake: Picard gives the mysterious girl some Earl Grey. She has it in hand only in one shot, the faraway one when the two Romulan servants are leaving. The way the scene goes, at no point during the whole scene does she have time to even take a sip. (00:19:05)

Funeral at Fifty-Mile - S1-E22
Other mistake: It's a clear day not a stormy night as it should be when showing the barn in the flashback. Look closely and you can see a clear sky through the barn walls cracks.

Other mistake: During the 3-nightmare sequences, there are 25 students, with all desks full. However, 1 desk should have been left open as Kevin appears in the dreams, meaning there should only be 24 students.

Things You Can't Outrun - S1-E3
Other mistake: When Cisco and Cailtin call Barry to tell him about the man with the gun, Cailtin says he has a gun. Cut to the cops pursuing him, the perp shoots at the cops, and one of them seems surprised that he has a gun. There's no way Caitlin could have known about the gun without the cop knowing (which would presumably have been relayed over police communications).

Other mistake: When Tubbs and Castillo are talking in the entrance way of the Senator hotel, at the end of their dialogue Philip Michael Thomas makes a very clear gesture with his right hand, which is Don Johnson's cue to finish his phone call in the background and approach the others.

Other mistake: During the first dozen or so episodes, during the opening credits, Onizuka is shown spray-painting a picture of a woman on a wall, with the words "Love" and "Piece" written next to her. Obviously, "piece" is a mistranslation, and the wrong spelling. The correct text should read "Love" and "PEACE."

Other mistake: When Amuro exits the Gundam cockpit after successfully repelling Garma's forces, his hair is colored jet black instead of brown (nothing else in the scene changes color and it is a fairly mundane transition, so it's not a matter of light). (00:19:50)

Fruit of the Poisonous Tree - S1-E3
Other mistake: On the whiteboard under variant spellings, analyse has the y underlined in the first scene. In the following scenes the s is underlined.

Strategy X - S1-E1
Other mistake: When Nightcrawler pumps his fist in elation while standing in front of the mirror, his arm casts no reflection. (00:09:52)
