Don't Eat the Snow in Hawaii - S1-E1
Audio problem: Ensign Healy parts from Magnum saying "See you, Magnum", but his lips barely move, not long enough for all the words. (00:31:05)
Don't Eat the Snow in Hawaii: Part 2 - S1-E2
Audio problem: Rick sprays the hitman with bullets, and hits the car behind him. The car is not Robin's Ferrari, but regardless of that, the car alarm of the Ferrari stops the moment that black car is hit. (01:25:25)
China Doll - S1-E3
Audio problem: Sorting the whole 'protecting the vase' business when it's first brought up, Higgins asks "Is the vase Chinese?" The audio in the scene becomes really spotty, culminating with Magnum saying "Mai Ling" in audio, with Tom Selleck mouthing something else entirely. (00:17:40)
Thank Heaven for Little Girls and Big Ones Too - S1-E4
Audio problem: Magnum just took TC to the bad part of town. TC says "Hey, look, don't forget you called me, I didn't call you." with the audio noticeably much lower than the rest of the conversation, and out of synch with Roger E. Mosley's lips. (00:13:00)
Audio problem: The episode opens with a news report, which itself opens with the words; "In Belfast, Northern Ireland, where a bomb blast destroyed an office building last Tuesday, a special task force under the command of Brigadier General Alistair Folkes", etc. The report runs for a minute, then the phone rings and Higgins, off-camera, answers. The audio of the TV fades in and out to leave room to the relevant conversation, but you can still hear that it's going in a loop, repeating the exact sentence it started with and moving on from there word by word. (00:02:00)
Never Again... Never Again - S1-E7
Audio problem: In the episode montage that precedes the opening theme, Rick does his fake sushi delivery man schtick ringing the doorbell. The sound of the doorbell there is a buzzing sound different from the one used later in the actual episode. Which also is a single neat two-tone sound, in contrast with Larry Manetti pressing the button multiple times. (00:00:30 - 00:37:40)
Never Again... Never Again - S1-E7
Audio problem: The first time Magnum goes to the Honolulu hospital, the first sound in the building consists of an announcement; "Janet Clark, please report to Maternity, Janet Clark." The announcement is repeated throughout the scene Magnum is in the doctor's office at night, just as he switches off the lamp on top of the filing cabinet (by the life preserver), Janet Clark is paged in maternity again. (00:12:25 - 00:34:15)
Never Again... Never Again - S1-E7
Audio problem: During the close-up of the photo held by Rick, Magnum's voice saying "Her right arm" is dubbed in with a marked difference from the rest of the conversation (added in post - perhaps to specify which arm, or originally the wrong one was mentioned and they corrected the mistake, but the artifact is strikingly noticeable). (00:39:50)
Never Again... Never Again - S1-E7
Audio problem: When Magnum chases the boat that is taking off, he shouts something to Rick about the coast guard with Tom Selleck's lips not moving. (00:43:15)
Never Again... Never Again - S1-E7
Audio problem: During the climax with Lena on the boat defending their action, from "They have no right to hunt us like animals" onwards the parts of dialogue with Hanna Landy are dubbed later and with a very inconsistent audio level. (00:45:40)
The Ugliest Dog in Hawaii - S1-E8
Audio problem: During the car chase, the evil boss says a line "Well, there ain't gonna be no witnesses now, so be a good boy and pull that piece and get ready to use it." recorded at higher volume and 'flat' as opposed to variation of the street noises, making obvious that it was dubbed in later. (00:22:20)
The Ugliest Dog in Hawaii - S1-E8
Audio problem: In Higgins' study at the Nest, TC says "Sure is. And I got 450 bucks' worth of bullet holes in my bird to prove it." The two sentences overlap for a moment in an audio editing flub. (00:40:15)
Audio problem: In the highlight reel that comes before the opening, Mac's computer does a scrambled electronic sound different than the cleaner bleeping sound used in the actual episode. (00:00:05 - 00:11:50)
Audio problem: When Tobin receives the call from across the street, the agent in the long shot is talking without moving his lips. (00:02:25)
Audio problem: Magnum found Eric at the abandoned building. In their unlikely chase, at one point Magnum gets by a railing he ducks underneath to get - questionable - protection. If you look at the left of the frame, you can see the puff of smoke and debris that would imply a bullet being fired, but there's no audio for that. (00:28:50)
Audio problem: When she comes around at King Kamehameha and especially in the scene by the tidal pool, Rebecca Holden's lines are very noticeably dubbed in.
Audio problem: When Zeus (or Apollo) drops the towel, Magnum looks at him and says "Hi guy!" in dub, but Tom Selleck's mouth is simply open as he is breathing in some air. (00:17:25)
Audio problem: The young judge runs away from the guy he stabbed. He promptly then tells Diane "C'mon, get in the car, c'mon." Not only is the audio of different quality and dubbed later in studio, but Miguel Ferrer's lips don't move at all for the last part. (00:28:25)
Audio problem: In the shot when Bobby and Diane drive off, the exhaust fumes show the car is turned on before the opportune sound is inserted. (00:28:25)
Audio problem: Rick's incredulous "Help?" when Higgins offers his aid to Magnum, is dubbed in poorly and at a volume and ambience in contrast with the rest of the scene. (00:29:45)
