I also cannot find a way to export the audio with the video of a Flash file. I'm amazed they would not offer this option.

I tried importing audio from a video in Cool Edit Pro, but it only get the first audio clip in a file. So if the flash has an intro, only the intro will get imported.

I also tried exporting the audio from Winamp. It seemed okay, but I got stuttering inbetween clips and the whole thing cut off really early.

Argh...I'm still trying though.
