Narrative:

First officer made a PA for flight attendants to be seated for takeoff when #2 for takeoff and about 4 mins before rolling. Flight attendant called back to say 'we need a min.' about a min later, we were cleared onto runway and taxied much slower than normal onto runway. Noted that video monitor light was off. We were then cleared for takeoff. Later, were told that not all flight attendants were actually seated. Some missed communications here. We wish we had told flight attendants to call back when ready for departure. Time from pushback to takeoff was 15 mins.
