I created a video from a Hard Drive Video Camera which I imported into imovie to work with and from there to iDvd. I successfully burned my movie using iDvd and it can be played in any dvd player I have tried, however at work we have a mass DVD burner that for some reason says that my source disk is empty. Any suggestions on how I can fix this? Ive tried making about three different copies from the mac and no success. It would really be bad if all the movies I have made on my laptop cannot be copied anywhere but here. Thanks!
