I'm trying to burn this project I have made in iMovie and iDVD. I have everything ready to go, but when I insert the blank DVD-R, the computer spits it back out. When I just insert the disc without iDVD open, I get the little popup that tells me I have inserted a blank DVD, and ask me what i would like to do. Is there any way that I can burn this and watch it on a consumer home system? I have to present this to my boss at 10am tomorrow. Help!!
