I have a late 2010 iMac running Lion and am strongly considering a Mavericks upgrade to take advantage of functionality with my iPhone 5 and iPad Air. I have the need for burning home movies created in iMovie to iDVD. Ignoring the fact that there is quite a bit of disagreement over whether Apple should support iDVD or not, the fact is, I will need it for the foreseeable future. A simple Google search regarding iDVD compatibility with Mavericks yields quite a plethora of opinions. The usual horror stories about no compatibility and then others who report things as just fine. The situation seems to be complicated by the apparent elimination of the option to share out of iMovie v.10 to iDVD. So trusting this forum as I have in the past, I am wondering the following: 1.) If I upgrade to Mavericks and leave everything else alone (i.e. keep iMovie 9.09), should iMovie and iDVD continue to function as usual? 2.) If I upgrade to Mavericks, and then to iMovie v.10 at some point in the future, what is the protocol for getting movies out of iMovie to iDVD? Sorry if this is confusing or sounds nit picky. I just like to understand what I'm up against in terms of operational issues, before I upgrade to any new OS. Thanks for the help.
