Why is the image so jerky?

Yes, it has to do with the 24 fps movie converted to a 60 fps display.

All movies are shot at 24 fps where tv bradcast is shot at 60 fps. Thats why you are going to notice it on movies and not tv broadcast.

Its actually nothing to do with blu ray discs. I've noticed it on standard definition dvds. Two examples are Master and Comander, when the ship is panning through the screen from right to left. Another exaple is in Spiderman 2 at the opening credits.

I'm actually surprised you are seeing it on an LCD screen. The jerky effect is very noticeable on dlps, but since LCDs have pixels with very slow refresh rates, it should not be as noticeable.

I think the only way to get rid of it is getting a display capable of slowing down to 24 fps.
