Exporting IMovie to Flash Drive vie IDVD for Burning on Another Computer

I have made a slide show in IMovie and since my computer can't burn a DVD, I would now like to export the IMovie to IDVD and then onto a flash drive so that I am able to burn on another computer (probably a PC). Which is the best format to put the movie in for export via flash drive and how can I create the appropriate file after transfering the IMovie to IDVD. There didn't seem to be an export or share option for me on IDVD. If someone could help with the steps after sending the IMovie to IDVD. Thank you.
