SoundSoap and iMovie 08

[auscop]

OK, Am I missing something? I am in the middle of making a DVD and I needed to remove background hiss. After Googling for awhile I found that SoundSoap was a good product to do this and they advertise it works with many MAC applications, including iMovie. After doing the right thing and buying it I find their only instructions for working with sound in iMovie is with the previous version, (iMovie HD). I worked for hours trying to get the sound extracted so I can clean up the audio. Am I being blind to the obvious or did I just get ripped of $129 for an APP that is out dated? Yes I could encode the entire thing in iMovie 08, create the movie, import it to iMovie HD, only then to create my DVD.. I am hoping though if I just paid $129 there will be an easier way that I am just being too plain dumb to see..

Help anyone!!!!

Thanks in advance..
