Well at least I'm not alone. In my case, my pop-up layer appears, and the video frame appears complete with a big play-arrow, but nothing happens when you click it. I should add that the problems with the animations I mentioned above have now been cured. For whatever reason, I found that by going back into WD, opening the placeholder's HTML section, then re-saving it, seemed to fix whatever was wrong. It was if if just didn't save the swf file originally. Weird. Yes, I agree, IE8's share continues to drop but unfortunately it is still at about 25%.
