Cannot make a copy of dvd I burned with IDVD from ILife '09.

Are you trying to make a one-to-one copy of the actual DVD disk? If Toast won't do that then there is something wrong on the disk.

Or are you trying to burn an extra copy from the disk image?

Have you tried using Disk Utility?

To create an image file, launch Disk Utility and select File: New: Disk Image From Folder. In the window that appears, navigate to the desired folder and then click on Image. Give the image file a name, and click on Save when prompted. That’s it.

How to copy previously-burned DVD-R video discs

In terms of making copies, no, but in terms of compatibility with other DVD players, yes.

For the future, you may wish to have another way too back up your videos. DVDs are relatively fragile, and as you are discovering, have errors introduced during the burning process. Some concepts to consider are:

- creating disc images (a virtual DVD) and copying that for the physical DVDs.

- exporting a full quality/full size Quicktime file from iMovie and saving onto an external HD that can be safely stored somewhere.

- exporting your edited iMovie back to the camcorder and record it on tape.

There are other options, but personally I prefer external hard drives to store the image files (for quick copies) and the original iMovie files (for max flexibility in the future).

clicked the support link, followed the instructions, and it worked fine, although yet to play dvd from start to finish and check for any errors.

nice work Traus1!

Also I forgot to mention that the dvd player application must also be closed, otherwise the disk utility will not be able to create an image.

I'm having same problem. Since I updated ILIFE and Leopard anything I copy on DVD or CD will not duplicate from master.

Have you found an answer?
