I've tried burning a DVD+R of slideshows from iDVD 5.0.1 three times. Each time the window pops down that says: "current operation- image incomplete" The DVD comes out finished and ready to play on any DVD player, but I can't make copies of it now. The DVD Duplicator won't read it??? And to make more on iDVD, I'd have to go through the entire process again. I have to fix this asap for school... Please help.
