Which version of iMovie to use? I have a G4 Powerbook with iMovie (can't remember the version number) but it does allow for multiple sound layers. It also has firewire - which means I can use Mini DV. My intel macbook (no firewire) has iMovie08 and iMovie09. I have heard these are not as good as the older iMovie - I haven't actually used either of these apps yet, but the interface seems much simpler than the older one, also seems to have less stuff (transitions, effects, etc) Is there any reason to use the newer iMovie versions?
