Finally after a whole lot of trial and error, I created the perfect slideshow. Next came what I thought would be the easy part...uploading to YouTube. Not! Everything I have tried fails miserably. Every file format I convert to is not recognized by YouTube. Tried exporting as Flash with .swf extension, tried pdf...no good. YouTube requires Flash presentations to be uploaded in the .flv format. How the heck do I convert my Impress Slideshow into the .flv format? Edited to remove All Caps (TheGurkha, Moderator).
