I'm playing this on the PS3.

Is it normal for the introduction video (the one that plays when you start a New game, and opens with the text "1958 Beneath the Atlantic Ocean) to be kind of choppy? It's not horrible, but you can still tell that it's hanging on frames of animation or skipping frames of animation. The movement isn't very smooth and it's somewhat jerky.

I found it most noticeable at around 1:28 when you turn at the stairs, and around 1:54 when you enter the party. I'm linking this video to show the points I'm referring to, not necessarily to check if THAT video is choppy.

The in-game visuals run fine, it's just the introduction video I'm curious about.
