Burns in iDVD,iTunes,and Toast 6. No additional drivers or updates needed. This is an brand new OEM drive, so no pretty Mfg box, but install instructions and PC software. As of this morning, still $110.00 USD, plus shipping. Take a look. http://www.buyxtremegear.com/dvra06.html Listed below is the ASP report. CD-RW/DVD-R Disc Burning Fully supported.
