funny, so i installed imovie from ilife 09, and reconnected my camera.
it recognized the camera and then a surprise....
it could see my sd footage from the drive, but not my avchd footage, regardless if the camera was set to hd or sd... i could import the sd footage no problem, did relatively well.
i have never seen imovie not show all the footage, both my macpro and mbp show all the footage when connected, so i guess there must be a switch in imovie that doesn't show the avchd when it isn't supported, which according to ilife is minimum intel core duo.
so you can go to town all day in SD, but don't expect hd... which, i would think would be pretty obvious with the little bitty mini.
