Are you trying to install iMovie from the "bundled software" package? The main package usually checks the machine type which would explain the error you're getting. You might be able to bypass this by running the iMovie installer directly.
First you have to look for the installer. There are two possible locations:
Install DVD 1 -> /System/Installation/Packages
Install DVD 2 -> /Packages (this is hidden). To access it, put in Disc 2. Go to the "Go" Finder menu and choose "Go to Folder". Drag the disc into the text box so it adds in the path to the cd and then append "/Packages" (without the quotes) and hit enter.
Look for the file named iMovie.mpkg (or something similar). If you try to run it, you may get the install error.
If you do, right click on the package and choose ""Show Package Contents". Navigate through the folders until you find a folder containing .pkg installers (here on my MacBook install cd it's in /Contents/Installers). You can then run the individual installers for iMovie and it's related files and they should install fine.
