coupla questions, 1. Can I load imovies 4 on a used iMac (256k ram, 30 gigs, 500mhz, G3, etc) 2. Better yet, will final cut express work (the specs say i need at least a G4, but the imac is a G3-any way to get around that). 3. Does imovie have voice over lay (in other words, can I have a person on screen, but over lay with another person speaking?) Thanks guys.
