Other mistake: When Veronica and Lilly find the camera in Echoll's guest house they show it on the ceiling fan pointing down on the bed. When they view the tapes of Aaron and Lilly in bed the camera view is coming from the cabinet and not from above them.

Other mistake: When Beaver takes the iPod/camera, the pictures are left on Veronica's laptop. This would only be possible if the pictures were copied onto the computer. It would have taken a considerable amount of time for all of the two thousand photos to be copied. There is the possibility that Beaver copied the three or so photos of Logan, but considering his anger, that's hardly something that he would take the time to do.
Other mistake: Season 1, episode 19, Hot Dogs. After Veronica bugs the Spanish-speaking man who returned the dog in the park, a shot of her laptop is shown. It's the exact same shot as when Veronica was helping the valedictorian front-runner find out who was harassing her. There are books and even the girl she was helping in the shot, proving that the shot was not in Veronica's car, as seen in the very next subsequent shot.
Other mistake: Keith tells Veronica that Woody's password is "mrgoodwood." When she types it in, 11 characters are entered, but the password is only 10 characters long. It can't be a "." because Mac OS doesn't use that character in passwords.
