[NTG-context] including swf files?

Hi, out of curiosity: how do I include a swf file into a pdf? So I can click on 'play' (or wherever) to start it? I have seen x-res-50.tex and created a PDF file using the example, but I'd like to have such an animation within my other documents. Does anybody know why acroread 7/mac asks for media player for flash? I have done all updates for my mac (10.4.3, qt 7). Patrick -- ConTeXt wiki and more: http://contextgarden.net
