I have one of each, and am pretty happy.... withthe exception that I purchased the drives as "OEM": just the drive, no software, no drivers.
For DVDRAM formatting I need the software. (DvdForm).
FOR DVDRAM read/write on Windows XP pro, I need driver. (it seems!)
LGE support on their web site is limited: only firmware updates, and manual, no drivers!
Could a good soul, make a bittorent file of the LG support CD for these products, and post here about it?
