How to install iDVD on OS X Yosemite or Mavericks? I have an old Macbook with Snow Leopard on it, and a newer Macbook Air with Yosemite, and a newer Macbook Pro with Mavericks.

The old Macbook is taking about 4 hours to encode videos to burn to a DVD disc using the highest quality setting, so I wonder if I install it on the Macbook Pro, whether it can be much faster.  However, since iDVD is discontinued since Lion, there might be 2 ways to install it on the Macbook Pro or Macbook Air and I wonder if they will work.


Buy iLife 11 (produced in 2011) from Amazon and install on Mavericks and Yosemite... but I wonder how compatible it will be, and whether the installation may write some outdated material over the newer, more current files (of the OS).
Simply copy the iDVD app from the Applications folder on the Snow Leopard machine to a USB Flash drive and copy it over to the Applications folder of the Mavericks and Yosemite machine.  But is there any side effects of doing so?  Often, the way general users install apps on the Mac is by download a .dmg file, and double click to see a virtual disc, and then just drag the app (which is actually a folder) to the Applications folder. So if I do the method (2) here, isn't the same as the .dmg way of installing an app?
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.
