Red Rackham's Treasure - S1-E5

The Crab with the Golden Claws: Part 2 - S1-E2
Audio problem: In the "previously on Tintin" segment, when it recaps the three bad guys appearing to kill Daws, one of them says "You disappoint us, Daws." The voice of the person saying the line is significantly different to what was heard the in the previous episode. (00:02:05 - 00:23:40)
The Crab with the Golden Claws: Part 1 - S1-E1
Audio problem: As Snowy chews through the ropes keeping Tintin tied up, Tintin removes them and then says to Snowy "We've got to find a way off this ship. We've stumbled into a real hornet's nest, here." Snowy then replies with a bark, but his mouth is completely sealed shut and there is a rope in his mouth. For Snowy's bark to be possible, his mouth would had to have been open. (00:13:15)
The Crab with the Golden Claws: Part 1 - S1-E1
Audio problem: When Thomson and Thompson are phoning Tintin to tell him about Daws and the Karaboudjan, Tintin hangs up and makes for the docks. Thompson then says "He hung up" and Thomson starts tutting. Neither of their lips move during this line or the tutting. (00:07:50)

The Calculus Affair: Part 2 - S1-E13
Audio problem: When Tintin, Haddock and Calculus exit the hospital, Haddock says "Blistering barnacles, I'm glad to be out of there. The food was terrible". His mouth doesn't move when he says "The food was terrible". (00:25:50)

The Calculus Affair: Part 1 - S1-E12

Audio problem: The first shot after the "previously" shows the burned down club. A further two shots after this shows Snowy growling at Mueller and his partner in crime. His mouth never moves when he does this. A growl like that would require his mouth to open at least a good few inches. (00:25:25)
The Black Island: Part 1 - S1-E10
Audio problem: Tintin is shown tying Mueller and his partner in crime to a tree with a cable. After he finishes saying "This old cable should hold you for now", we can see his mouth move as if he is speaking before he goes onto the next sentence even though he isn't actually saying anything. (00:20:45)
The Black Island: Part 1 - S1-E10
Audio problem: After Mueller's assistant gets knocked out by stepping on a rake, Tintin looks at Mueller and says "That was close". Look at his mouth when he says this. His mouth opens but as he says the line, his mouth doesn't continue to move along with the line. (00:20:40)
The Black Island: Part 1 - S1-E10
