Erhm... Jaguar is perfect on my TiBook 500, Quartz Extreme was perfect on the TiBook 800, I guess it rocks on the TiBook 1000. The SuperDrive, as you can read on apple.com, is a 1x DVD write drive, so it's as fast as the first SuperDrives used and half as fast as current iMacs' and PowerMacs' drives. The 'support' of SuperDrive in Jaguar is excellent, meaning you can use iDVD or DVD Studio Pro, but you can also write (data) DVDs from the Finder, through Disk Copy or a third party utility like Roxio's Toast 5.2.
