Continuity mistake: Samantha is wearing black pantyhose when she pulls Carrie into the bathroom to tell her about her bad dye job on her crotch. Then she pulls up her skirt to show Carrie, and her legs are bare.
Visible crew/equipment: When Charlotte leaves her apartment building on the way to the party, she puts on large sunglasses. You can see what appears to be camera equipment, in the reflection of the plastic lenses. There are two white squares, which look like a camera light and filter screen. (00:22:20)
Visible crew/equipment: When Carrie and Aleksander arrive at the museum, he turns to close the cab door and his back is facing us. You can see the outline of a long cable running vertically down the center of his back, protruding from under his jacket. This cable goes from his neck down to the bottom flap of his jacket, and must be part of his mic. (00:31:00)
Answer: I'm a long-time fan of the show, having re-watched it many times, and I definitely remember slightly different dialogue at the end of that episode than what's on my DVD. I'm afraid I have no idea why this change might have been made or any other info, but you're not insane.
