Update iMovie in OS X 10.6.8 My iMac is running OS X 10.6.8 (Snow Leopard).  I still have iMovie 7.1.4. How do I update it? And which version of iMovie is it compatible with OS X 10.6.8?
You can get the iMovie 8.0.6 from Apple website

You can also buy it on Amazon, the "iLife 11" package that contains iMovie 09 version.
