PSD sequence from AE to Flash with transparent background - total fail, Please Help!


I’ve done a complex animation in After Effects and want this to be part of a Flash movie, running on timeline as a sequence.
So I rendered this as a PSD sequence (RGB+alpha) with hoping, this has transparent background in Flash.
But Flash seems not understanding about alpha layers and displays black background instead of no-background. I also rendered this as PNG sequence but failed again – the images opened in wrong size and were really huge, so Flash Player wouldn’t play it smoothly.

Then I saved just a frame as Photoshop Layers which after importing to Flash has transparency in it. Sure, doing it frame-by-frame is a time consuming process and feels stupid way to do.

I guess at this point a little help is really needed.
