The two examples of code below are an attempt to highlight the problem. It
is currently troublesome to build a frame advance method using pause, it is
better to use speed(0) at the moment.

The code was copied over the MoviePlayback example in each case

//Intended successful result
import processing.video.*;
Movie myMovie;
void setup(){
size(200, 200);
background(0);
myMovie = new Movie(this, "station.mov");
myMovie.loop();
myMovie.speed(0);
}
void movieEvent(Movie myMovie){
myMovie.read();
}
void draw(){
image(myMovie, 0, 0, width, height);
}
void keyPressed(){
myMovie.jump((myMovie.time() + 0.1) % myMovie.duration());
}

//faliure
import processing.video.*;
Movie myMovie;
void setup(){
size(200, 200);
background(0);
myMovie = new Movie(this, "station.mov");
myMovie.loop();
myMovie.pause();
}
void movieEvent(Movie myMovie){
myMovie.read();
}
void draw(){
image(myMovie, 0, 0, width, height);
}
void keyPressed(){
//takes at least 20 presses to get an image
myMovie.play();
myMovie.jump((myMovie.time() + 0.1) % myMovie.duration());
myMovie.pause();
}

original thread with additional information:
http://processing.org/discourse/yabb_beta/YaBB.cgi?board=VideoCamera;action=display;num=1115664520

also includes details of the workaround.

The link into the discourse board (below) is no longer working. I've not
seen that before. Do you think the post was moved or changed? Anyway, I
also noticed this bug, but saw that it was already reported.

looks like the post was deleted, probably when the boards were moved
around. the error is because you had renamed the VideoCamera board to
Video, so it's getting weirded out.

i believe the workaround is to set the rate of the movie to zero, and then
later set it to 1.

closing this bug, because we'll be replacing the current video library with
another sometime later this summer. as such, i won't be doing any more bug
fixes on the current video library. in the meantime, we recommend using
gsvideo, opencv, or one of the other video libraries that are available.
