I haven't forgotten about you. I have looked up methods of trying to download the .swf, but I don't seem to be able to get hold of a good method. I will, however, still be pursuing answers. Sorry for any inconvenience.
Download format factory and Audacity. When you find the youtube video
type
http://www.
ssyoutube.com/watch?v=w65ZOJsk5pI not the link i pt for example but ss inbetween w. and youtube.
Change the Files format to OGG.
Then edit it with Audacity.
