thank you, jim and linda, for your quick replies. i just checked and no, i did not have "Synchronize slideshow to music duration" checked. i think i assumed that meant that it would be done automatically (even though i now see that it says 'custom' below it). the way i did it was individually inputting the seconds and milliseconds for each slide, using the slide's "customize slide" button. so for instance, i begin with a title slide exposed for 6 seconds, followed by a slide that is set for 4 sec and 250 ms and has the music starting along with it, followed by a slide set for 7 sec and 800 ms and so on and so forth for 88 slides. so i tried to avoid making the software synch the music with the slide transition, as i observed that to be making the music skip and produce other small errors. so i did it myself, by setting each slide time to go along with, what i made to be static, the mp3 times. from my very basic understanding of the software, i did do a custom synchronization, and it worked (on my computer). but would it work better if i actually checked the box and used the timeline etc (which i now wish i had looked into 4 weeks ago)? i assume it would have saved me a lot of time, but would it help in this case? from what linda is saying, it sounds like i might be out of luck anyway. would you recommend downloading the newest version of the software and trying to make it into a movie? i have a dvd burner... thanks again for your help
