Factual error: Molly and Ramsey find out that the van they are looking for was ticketed in Baltimore City at "the corner of Pennington and Fifth," and they are looking at a computerized map of the area. However, the map can be easily matched up to the actual Mapquest map of the area around the corner of Fifth St. and Patapsco Ave., except that the latter has been relabeled as Pennington. There is a Pennington Ave. in Baltimore City, but it runs parallel to Fifth, about a mile east of it.
Continuity mistake: Colonel Gathers says to Brock Samson, "You're not in the Marines anymore." But in the earlier episode, "Past Tense," after the credits, there is a flashback to college again and Brock says, "I'm off to join the Army"
Forever Red - S1-E34
Plot hole: Tommy states that he and the other Zeo Rangers destroyed the Machine Empire's leaders and ultimately destroyed the Machine Empire except for the Generals who escaped. This is not true - Lord Zedd and Rita destroyed the Machine Empire leaders at the end of series 4, and the Space Rangers destroyed them again in Countdown to Destruction in series 6. The Zeo Rangers never destroyed the Machine Empire.
Suggested correction: How would Tommy know that? He didn't watch the show or know the ins and outs of what happened in space. This is what he believed based on his experiences on Earth. Everything you described is factually correct, but Tommy did not witness this. So, to his knowledge, he destroyed the Machine Empire.
Factual error: There is no physical way that Steve Austin could perform most of his superhuman feats of strength in the ABC television series, due to the fact that they simply replaced his arm and legs, but didn't rebuild or reinforce the rest of his skeleton and muscles to handle the physical loads. Interestingly, author Martin Caidin (creator of Steve Austin in his novel, "Cyborg") actually did describe an incredibly complex whole-body rebuild that included vertebral reinforcement and ribcage and pelvis replacement, which was far more scientifically-accurate than the subsequent ABC television interpretation. ABC only accepted the series on the condition that it was less technical for their audience.
Continuity mistake: Ava spills Coke on her blouse and creates a big circular stain. As she walks to the bathroom, the stain becomes a long narrow one. When she is leaving the pizza place, the stain is still narrow, but much shorter. (00:21:00 - 00:22:00)
Continuity mistake: In season 4 of Prison Break, Mike Scofield's tombstone date of death shows 11-4-2005 but in this the date is 11-4-2010.
Character mistake: The Enterprise is targeted by projectiles from the planet. Spock identifies them as "plasma torpedoes", and Captain Pike reacts with surprise; "Plasma torpedoes? That's 21st century tech" and from that they all establish that the civilization they contacted is not yet capable of warp drive. Plasma torpedoes are the main weaponry of the Romulans centuries later, and Earth itself did acquire warp drive in the 21st century, so this claim and deduction don't seem to add up. (00:22:15)
Other mistake: If you look closely at the army of Rangers in the opening credits, you can see four versions of Tommy Oliver: Green Ranger, White Ranger, Zeo Ranger Red, Black Dino Ranger. Even though he had a single clone made, he can't be four variations at the same time.
Revealing mistake: The swords Jayden and Dekker use often bend when striking each other, revealing they are rubber blades and not metal.
Continuity mistake: The 4 Space Rangers (Carlos, TJ, Cassie, Ashley) morph on the overhanging gangway, then jump off to the ground below. We see them hit the ground, and in the very next shot, they're right next to the Galaxy Rangers, and Andross, who are on the other side of the courtyard. There wasn't enough time for them to move that distance.
Visible crew/equipment: Diamond parks outside the apartment house, and when he opens the car door, it mirrors several stage lights and reflectors.
Delenda Est - S3-E11
Revealing mistake: When Dylan and Tyr head to a bridge where supposedly the power source is located as well as Rommie, they start to cross the bridge. As the camera is facing Dylan and Tyr, the next scene two aliens teleport in. Rewind the video to facing Dylan and Tyr and play in slow motion. Watch the bottom portion of the screen and notice the top portion of one of the alien's head go into the camera as if the aliens walked into position for the teleportation.
K is for Kill: The Tiger Awakes (1) - S2-E8
Visible crew/equipment: Steed is seen driving along with Purdey and Gambit in rural France. The camera was probably mounted on the front passenger side door, pointing in. As they near their destination, the camera pans to reveal a farm house, and as it pans, a professional-looking microphone can be seen sitting on the dashboard.
Plot hole: At the end of the episode when Tommy has change the witches into little statues, he's a werewolf. Then he runs to Stacey and changes back. However, in Hello Nasty it takes a Haiku from Merton to change Tommy back.
Factual error: One of the naked female dancers at the party has breast implants. Although some forms of plastic surgery were known to the Romans, breast augmentation was not one of them. If you want to check for yourself she appears just after the masked dwarf moves through the shot.
Continuity mistake: The packages Drake and Kathy place on the table beside their coats have disappeared when they return for the coats a few shots later. (00:19:00 - 00:21:20)
Other mistake: When Jessica calls Hondo to let him know about Deacon's wife, you see Hondo answer the phone normally. Right after she tells him what's up, you can see him holding the phone upside down, with the camera lens towards the bottom. (00:24:30)
Who Killed Avery Lord? - S1-E23
Visible crew/equipment: After the woman in the negligeé goes back into her apartment, a crew member's shadow appears on the corridor wall. (00:42:00)
Continuity mistake: When Stephanie runs in and sees 'Jim' on the floor there is a huge puddle of blood on the floor. When 'Jim' changes back into Amelia the puddle disappears.
Remembrance - S1-E1
Character mistake: Picard and Data are playing poker at the beginning of the episode. Before the actual faces of the players are revealed, we are shown close-ups of their hands as they put down the chips for the bet. When Picard says his first line in the series it's "See", and it is literally true, because in the previous shot, Data put his 5 cards down on the table and face up. (00:00:50)
