Please take a look at a video tutorial and compare the resulting SWF it with my reproduction of it.
My version: http://www.discretedata.com/navBar1/flash/FlashEffSlideShow.html
My FLA: http://www.discretedata.com/navBar1/flash/FlashEffSlideShow.fla
For the tutorial, I needed to dbl-click on the "Play in HD Quality" button which opens it in Quicktime or whatever (It doesn't have a hover state but it is a button). It took me almost 2 minutes for it to open and load fully, but with this one you can go right to the 14-minute mark to see what the SWF should really look like.
Mine is very close to theirs except there's about a 2-second lag between images in mine. I've triple-checked my settings in FlashEff and the (minimal) AS, but I can't see any discrepancies. So I'm hoping that a fresh set of eyes can see what's missing in mine.
Please let me know what I have to change in order to close up the gap between the images.
