You need about 10 gigs of free space on your boot drive. Have you tried to make a disk image of the DVD and then burn the image? Open up the Disk Utility and with the DVD mounted, under Images choose New Image>From Device, then save it on your big external HD. You should be able to burn the image without any trouble. regards, sb On 2/21/05 11:26 PM, "Lanny Cotler" <lcotler at willitsonline.com> wrote: > Dear Friends, > > I'm in a bit of bind trying to copy a DVD.
