To copy a DVD that I’ve made in iDVD after I’ve already deleted the source material and DVD project files:nn
- Insert the master DVD.
- Fire up Disk Utility.
- Select the DVD in the Source menu.
- Click the New Image button in the Toolbar.
- In the dialogue sheet that follows, name the disc, select “CD/DVD Master” from the type list, and “none” for the encryption option.
- Rip the image, then burn it to a blank, also using Disk Utility.
That’s it.
