If you have a Mac with a G4 processor that has a CD drive and no DVD drive, you won't be able to install iLife '06 because the computer won't recognize the iLife '06 Install DVD disc. This can include certain model eMac computers and early model PowerBook G4 computers.
Unlike previous versions of iLife, there is no iLife '06 Install CD. There is only an iLife '06 Install DVD. Make sure that your computer meets the minimum requirements for installing iLife '06. If you have another computer with a DVD drive and if all requirements are met except the DVD drive, you can do one of the following:
Use target disk mode for the install.
Copy to a network or external drive to install.
Use another computer with a DVD drive, and drag iLife '06 Install DVD to any of the following with at least 10 GB of free disk space:
When the copy is complete, you can install iLife '06 from the volume above on the computer without a DVD drive.
Connect and install using file sharing.
If your computers aren't already connected to a network, see this document for information on creating a small network.
