My slideshow contains both still pics and video clips. The problem being: during preview/playback the timeline marker continues to advance past the video clip while the clip is still playing. The result is that when the video clip finally completes, the slides following the video flash by at hyperspeed until the preview/playback catches up to where the timeline marker has advanced. At that point the playback proceeds normally until the next video clip when the overlap problem repeats.
Incidentally, I've just updated to the latest version (6.39) from 3.0 -- quite a jump I know -- so maybe that has something to do with it?
Anyhow, any help would be appreciated. Thanks =)
