iTunes opens automatically when CD inserted I don't use iTunes, but I can't prevent it from automatically opening every time a CD is inserted. 

I have already changed the system preferences for when a CD/DVD is inserted to "ignore" or to "open other program"-- but it seems that iTunes 12 overrides these system preferences.  

I've also looked at the preferences within iTunes, but there is no option to "ignore" when CD is inserted (though I am almost certain there used to be!)
Try changing the system preference (as per your screenshot) for "when you insert a music CD" (or whichever one is causing you an issue) to "Open in iTunes" and then immediately back to "Ignore". For me that seemed to reset the preference to ignore.
