15.1. Why iDVD?You already know from Chapter 11 that you can export your finished iMovie project back to a good old VHS cassette, one of the world's most sure-fire distribution methods . But VHS tapes are quickly becoming old news. Why mess around with clunky old tapes when you can produce cool, shiny discs? Producing your work on DVDs offers a boatload of benefits:
Still, there are a few reasons to pause before committing your work to DVD. For one thing, homemade DVDs don't work in quite as many DVD players as commercially pressed discs do. Stick an iDVD production into an older DVD player, and you may see the dreaded "No Disc" message on the TV screen. (In this regard, DVD-RW discsthe ones that you can erase and rerecord over and overare worse than DVD-Rs, which you can record on only once.) DVD players sold since 2002 are generally a safe bet, but check the master player compatibility list at www.videohelp.com if you're ever in doubt. (Some players are fussy about which DVD-R brand discs they'll play, too. Here again, sticking with brand names like Verbatim is your best bet.) 15.1.1. Getting iDVD 6If you own iMovie 6, that means you also have iDVD 6, because they both come on the same iLife DVD from Apple. In addition to a DVD burner , iDVD requires a Mac with a G4 chip (733 megahertz or faster), G5 chip, or Intel chip inside, plus 256 MB of memory or more preferably a lot more. Few programs rely on computing horsepower as much as iDVD, so faster computers work a lot better than slow ones. iDVD also requires Mac OS X 10.3.9 or later or Mac OS X 10.4.3 or later to run, and 10.4.4 or later to create widescreen DVDs. |
