Under "custom animations", I am able to specify the 999 slides...but that is
all from your notes. I don't see "play settings", "play using animation
order", or "continue slideshow".
After specifying the number of slides, the visual portion of the movie does
continue from slide to slide, but the sound starts over each time.
I didn't specify before, but I am using PowerPoint 2003. I have also tried
both a 'movie clip' and also a 'windows media audio/video file'. The sound
starts over on each slide, but the visual portion is continuous.
