I made a slideshow in iMovie and burned it to disk but won't play?

Hi Jim - Do you mean you burned a DVD or just exported the movie to a file on your hard disk? Either way, I would imagine you'd need to provide a little more information for anyone to troubleshoot whatever may be wrong there.. I've attached a link to a recent iMovie course [above], maybe there'll be something useful in there [there's a section on finalizing/exporting], or perhaps a regular iMovie user will have a suggestion..
