Audio Issues?

For the Ignite presentation, I was not able to get my audio to play once I uploaded my presentation to the Wiki.  I don't know if anyone else had this issue as well, but if you did…

I found that if you

1) save the slide show as a movie

2) import this movie into iMovie

...then you can add songs from iTunes and record the narration on top of the powerpoint video using iMovie.  (This should also work with Windows Movie Maker.)  

I'm not sure if there is an easier way to get the audio to work when it is downloaded from the Wiki, but I just thought I would share!
