How to install iDVD on OS X Yosemite or Mavericks?
iDVD still runs on Yosemite. I haven't tested to see whether it still actually functions correctly, as I have no DVD video player to view the result on.

Edit 2017: This method apparently still works on Sierra, but I haven't tested.

I would go for the 'sneaker-net' method of install…
copy the app to a USB key &amp; carry it over to one of the other machines.  Will take 2 minutes to discover if that works.

Edit
I trawled my boot drive for associated items for iDVD

It appears that the themes, which would be installed by the installer live in
/Library/Application Support/iDVD/Themes &amp; ~/Library/Application Support/iDVD/Installed Themes In folders by version, iDVD 4, 5, 6, 7 etc

It would be a simple-enough task to carry these over in the same way.
