If so, I found the only way to make this easy for me was to upgrade to iLife '08 (in order to get iMovie'08) AND upgrade to Leopard. Now, when I plug in my Everio and open iMovie '08, the movies backup to my iMac as easy as when I download photos.
I thought I'd save money by purchasing the third-party software from Pixela Corporation called CAPTY MPEG Edit EX) -- this alternative solution is mentioned by JVC on their website ( http://support.jvc.com/consumer/support/support.jsp?pageID=1&item=13#169). This was a waste of money because then the whole project of downloading and converting files became too burdensome. The idea was to make this easy! So, I finally upgraded last week and successfully downloaded over 400 video clips that I had stored on the Everio. I will work on my first project this weekend.
Good luck -- I know how frustrated you probably are.
Good luck.
