All the King's Horses - S2-E10
Audio problem: When McGarrett and Danno pull away from the curb in McGarrett's big black Mercury, the tire-squealing sound effect begins before the car actually starts to move. (Doesn't happen unless you're flooring it and "peeling out," which they're not.) (00:41:50)
Guess Who's Coming to Rio? - S2-E13
Audio problem: When Katrina walks out of the building at the end and crosses the street to Dover's car, the sound of her boots on the pavement doesn't match the actual movement of her feet at all. (00:45:10)
