Howdy folks. My buddy is looking into getting a new 1GHz iMac to convert his VHS collection of vacation videos into DVDs. He is also going to be making a few videos for events for family and friends. We are getting a SD iMac, 17" and either 512 or 768MB of RAM. We will also be getting either a Dazzle Holywood or a Canopus ADVC-100 as a bridge to convert the videos. My questions is to anyone who has done similar projects using iMovie and iDVD: 1) What other accessories do you recommend to get? (e.g. I heard an external firewire drive is a big plus) 2) Is iMovie sufficient to do this type of a project? 3) How much disk space of data should we expect to use up? Thanks!
