Thank you all for your advice. We have since re-cued the show using the timeline, and haven't had any more synch issues with our computers. We have a slideshow posted on a website, and have heard from at least one person who cannot download the show and play it from their hard drive, but can play it directly off the website. I don't have access to their machine, and do not know what could cause this kind of behavior. Also, regarding Eddie's post, is there a limit to the file size that can be played back with accurate sync? Does anyone have guidelines for how large a file I could use and still be assured of maximum playability with other people's computers? Thanks again for everyone's feedback. Sincerely, Derrick Kolus
