Can't not open a previous iDVD project

Question

I have wedding project that I completed in March. I wanted to burn another copy. I double clicked, I tried to open in iDVD. It quickly loads themes and then the window pops "create new project, open existing project, etc. Can anyone help on this matter? It was stored on the Lacie hardrive and then I put it on my desktop. It would not open.

Answer 1

Do you have one of the DVDs that you burned in March?
If so, you can use that to burn another by making a Disk Image using Disk Utility:
Creating a disk image
You can use Disk Utility to create a disk image of a disk, volume, or folder. You can use disk images to move files from one computer to another or to send to other people in email messages.
You can also use a disk image to burn a CD or DVD disc to send to other people or to back up the contents of your disk so that you can restore it if something happens to your information.
When you create a disk image you choose the format of the image:
If you want to continue adding files to the disk image after it's created, choose read/write.
If you don't need to add more files to the disk image, choose read-only.
If you don't need to add more files to the image and you want to conserve space, choose compressed . The disk image takes up only as much space as the data on the image.
If you want to use the disk image with a third-party application, choose CD/DVD master. The disk image contains a copy of all sectors of the disk, whether they're used or not, and copies them to other CDs or DVDs bit for bit.
You can also create a blank disk image so that you can copy files to it later. See "Creating a blank disk image" for more information.
Be sure the files you want to protect are in the same folder in the Finder.
To create a disk image from a disk or volume, select it in the list of disks and volumes.
Choose File > New then the type of image you want to create.
To create a disk image from a folder, choose “Disk Image from Folder.” Select the folder you want, then click Image.
To create a disk image from a disk or volume, choose "Disk Image from disk name."
Type a name for the image and choose where you want to save the image.
Choose one of the disk formats from the Image Format pop-up menu.
To require a password to access the contents of the image, choose "AES-128 (recommended)" from the Encryption pop-up menu.
Click Save.
If you chose to use a password, enter it in the dialog that appears.
The name of the disk image is followed by the filename extension ".dmg."
Once you have created a disk image from your prior DVD, you can use that disk image to burn more copies of the DVD:
