Video & Flash

Hey,
I am working with some video in flash. And I am just importing the .mov files. I have a coupla questions.

  1. How can I have the movie load part way, and then start playing after say 20% of the movie is loaded? I cant figure this out for some reason.
  2. Is there any free way for me to convert files to .flv
    thats all I have time for for now please help with this.
