Flip Ultra HD and Mac Os X -- version 10.5

I had the same issue with my new ultra hd and my 2008 imac. Basically, I just downloaded flipshare from pure digital's website and all is good. Another problem I have run into is that when I first plug the camera in, it asks if I want to update the cameras software, when I click 'yes', it gives the error, "unable to update camera software."
Last but least, Imovie 08 gives an error when I try to import the movies. No biggie, I just double click on the "dcim" folder in the flip video folder of the camera and I can drag the videos to my desktop, then into Imovie.
So far, not the seamless experience I was expecting, as this unit is supposed to be 100% compatible with mac's.
