If video does not play or you have sound and no picture, download this file (ovulation_movieb.mov) and play in quicktime similar to lecture podcasts. Note that this is a long movie and it will not start to play before fully downloaded. You can however start it to play manually by clicking the controller after some of the movie is downloaded. The sound does not start for about 15 seconds of the video so just wait awhile before right clicking on the link above.
