Slowing down a swf file to examine a technique

Does anyone know how to slow down a SWF file so that you can step through the file one frame at a time. I basically want to look at how visual effects are created.

Just to make this clear i’m not looking for a way to look at fla files. I just want to be able to see how visual effects are created (fades/wipes/text effects/rollovers) etc.

I hope this isnt classed as copying, it’s not my intent to rip off anyone’s work, I am just interested in the technique. I get a lot of inspiration of stuff like MTV and will often pause playback (Tivo here) so that I can get a closer look at a effect that they have used.
