here's a link to the problem video: http://www.austentatiousproductions.com/
I made a short compilation in AE CS4 and rendered an flv file.
Then in Flash CS5.5 make the swf video which works perfectly in tests and in DW CS5.
Everytime I have uploaded flv videos they work fine but this swf video just has a big white oblong showing.
I have never had trouble with swf slideshows but this is using video footage.
