Any movie over about 1 hour and 50 minutes, and which has almost any kind of supplementary materials, save a simple menu, will require a DVD9. But, there are many movies which can easily fit on a DVD5, and some were intentionally mastered with lower resolution so as to fit on a DVD5. In theory, the capacity, without any significant down-rezzing, of a DVD5 is 2.0 hours, and the capacity, without any significant down- rezzing, of a DVD9 is 4.0 hours. Just as Beethoven's 9th was used as the putative maximum capacity of a CD, The Ten Commandments and Gone with the Wind were used as the putative capacity of a DVD9. Complete with "Overture" music, Act One, "Intermission" music, "Entre Act" music, Act Two and "Exit" music, and "Prologue", for TTC, those two films each run almost exactly 4.0 hours. Something like 3 hours and 59 minutes and a few seconds. While every DVD reader can read manufactured DVD5s and manufactured DVD9s, not all DVD readers can read burned DVD9s, although these may be able to read burned DVD5s, while some DVD readers can read only DVD-Rs (which are DVD5s, only), and hence no burned DVD9s at all. The DVD burners supplied with Quicksilver 2002s are capable of DVD-R burning and reading, but have problems with DVD+ media, which certainly includes DVD9s. As a personal policy, I usually discard the burner, if present, and install at least a Pioneer DVR-109, -110 or -111. The recent Lite-Ons have been very good, too, but I tend to reserve those for Hackintoshes. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
