As i read a lot of Information now about LG Drives and I'm new to LG i tried around a bit with my brand new drive. I read that the LG Burners generally do not support setting Booktype on DVD+RW Media, but i discovers the H42L does ! I burned a DVD+RW Disc just to test this and it's Booktype is DVD-ROM now. I burned with Nero, checked with Nero and DVDInfoPro, DVD-ROM Also since I'm using Nero to burn all my stuff and you can set the Booktype there there's no need for command line tools or whatsoever to change the Booktype every time you boot Windows.
Forgive me if this is no new Info
