I am having trouble syncing the audio from the original PowerPoint format to the Windows Media Video format. My presentation has about 28 slides. I set it up to where 18 slides have an audio track, (MP3,) playing throughout. In the animation pane, I set the audio clip to be stopped after 18 slides. Now, when I preview the slideshow, the audio stops right where I want it to. When I convert it to the Windows Media Video format, the audio keeps playing. It won't stop... Anyone have any ideas?
