As a new media specialist I want to be able to use imovie for a school project. I managed to purchase iLife06 since 08 and 09 were not compatible with my Mac. I have Mac OSX 10.4 Tiger on a PowerBookG4. I have no burner to use the iDVD program, and I need to have a DVD to play on the PCs at school. There are no Macs at the school. I can't afford a new Mac right now- what's the best fix? Most economical for my purposes since this is my nickel? External drive? Internal drive? Which ones? I'm a new user, so please don't overwhelm me with jargon. Thanks!
