Here is some more info:
Transitions - If you want to remove all transitions from a presentation,
select all slides in slide sorter view, choose Slide Show | Transition and
select No Transition in the Transition task pane (in PowerPoint 2002/03).
Custom Animation - If you want to remove all custom animations in a slide,
press Ctrl + A to select all elements in the slide. Then choose Slide Show |
Custom Animation. Delete all animations listed in the Custom Animation task
pane (in PowerPoint 2002/03).
Sounds - Check your transition task pane with each slide active to ascertain
that you have no transition sounds enabled. Also, if a sound plays along
with the entry of an element on slide, you probably have an event sound
inserted. Also, delete any sound icons within the presentation slides.
