So i've finally gotten around to backing up all my disneys (about time since they have already degraded some) and I wanted to add one of those read along flip books that were popular way back when (1969). This is a record--yes the large black vinyl thing and a 18 page storybook that you flip as the record is playing. Now my idea was to scan it in as a slide show but what I'm wondering is--is there a way to vary the interval between slide changes in the VCD slide show programs (say Ulead dvd picture show)? I want the Mp3 of the record to play in the background and have the slide change at the appropriate time. As near as I can tell the interval is fixed and constant--feel free to correct me if I'm wrong.

If anyone knows a good way to do this I would be grateful!
