the aid of a DVD service bureau. (DVD service bureaus are middlemen between you and the large replication plants, which don't deal directly with the public.) Technically, these companies offer two different services: ·Duplication.Duplicated discs are copies of your original DVD. Service bureaus use banks of DVD burners, fve or ten at a time, that churn out copy after copy on DVD-Rs (the same kinds of blanks as you used). You pay for materials and labor, usually by the hour. (Discs with less data burn quicker, producing more discs per hour.) This is the way to go if you need fewer than 100 copies of your disc. (On the other hand, remember that some DVD play- ers don't play DVD-R discs.) ·Replication.Replication is designed for huge numbers of copies: 200 and up. In this process, the company actually presses the DVDs just the way Hollywood movie studios do it--and the results play back in virtually every DVD player. Replicated discs are produced in factories. When replicated, the data from your master DVD-R is placed on a pressed 4.7 GB "DVD-5" disc--a standard DVDs, not a DVD-R. power users' clinic Professional Duplicating DVD-R, DVD+R, and Drutil Apple says that iDVD 5 can now record onto more kinds of blank DVDs than ever­not just DVD-R and DVD-RW, but also DVD+R and DVD+RW. (Both kinds of discs play on re- cent DVD players once they're burned. But most burners can record onto one format or the other--either "-" or "+." Thou- sands of people, not noticing the difference when they buy blanks at the store, inadver- tently buy the wrong kind--and they wind up being burned.) But not all Macs offer this new fexibility. You have to have the right kind of SuperDrive. So how can you tell? One quick way is to use Terminal, the Unix command program that comes with Mac OS X. It's in your ApplicationsUtilities folder. Once the program opens up, you see some Unix codes that end with a $ symbol. At this point, type drutil info and press Enter. You've just told Unix to run its drutil (disc recorder utility) program. Instantly, the window flls with useful information about your Mac's disc-recording equip- ment, including who manu- factured it (probably Pioneer). Near the end of this block of info, you can see, quite clearly, which kinds of DVD it can write (that is, burn). For example, it might say, "DVD-Write: -R, -RW, +R, +RW, BUFE, Test." If you see only "-R, -RW," then your Mac can't record on DVD+R and DVD+RW blanks. Shop accordingly. (At this point, you can quit Terminal, unless of course you have other Unix work to do.) chapter18:idvdsecrets 451
