While I was browsing today, I stumbled across a firmware upgrade that allows you to double the burning speed of your SuperDrive on your 12" or 15" (some 17" also) PowerBook. It also enables you to burn DVD-RAM and DVD-RW discs! Here's the link: http://superdrive.cynikal.net/ I tried it out with an Apple DVD-R disc, and it really does work! Apple cripples (sp?) the drive for heat reasons, presumably, and also power issues, but as long as you do the burning in a well ventilated area it works fine! The speed does decrease to 1x if you use cheap DVD media, but if you use Apple's or other high quality discs, it burns at 2x! It will also burn CDs at 16x as opposed to 8x. Here are the comparisons of Apple's version and the OEM version: Apple's -> OEM CD-ROM (reading): 24x -> 24x CD-R: 8x -> 16x CD-RW: 4x -> 4x DVD-ROM (reading): 8x -> 8x DVD-R: 1x -> 2x DVD-RW: N/A -> 1x DVD-RAM: N/A -> 2x I tested both the CD-R and the DVD-R and they both worked as said. Anyhow, I'm sure a lot of you probably know about this, but if not, have fun! In the off chance that the firmware upgrade doesn't work, the site also has a firmware downgrade, so you can revert to Apple's firmware.
