Act of valor was shot at 30p because it was shot before the 24p firmware upgrade came. They had no choice. It was retimed to 24p in post.
waterdonkey; this is an extended discussion, especially since you are coming from a TV aesthetic, which is simply different than the cinema aesthetic. Your sony should be defaulting to the correct shutter angle and speed (I believe those cameras can set both) however, I think they have to be overridden from just doing the settings we are speaking of. However the 60i(p) vs 24p and the jitter you see are different issues from that - the aesthetic is simply different than what you've been trained in and so used to seeing. I've worked with TV guys too, there is just a different standard and look in broadcast TV.
As for 30p, it's actually a reasonable choice for certain kinds of work; some corporate video demands 30p as sometimes the client doesn't care for the 24p look. That's unusual though; my rule of thumb is that I shoot 24p for everything, except when some B roll, I might use 30p and put it on a 24p timeline giving a very slight slow motion which gives everything a dreamy look, especially useful in music videos.
