Yup, that's what i tried. the philips/fujifilm dvd-r 8x. another thing you might want to do is to upgrade your firmware. i upgraded the firmware of the liteon sohw-1673s. one of the reasons for the upgrade is more compatibility with media.
saw the following information from lg's website
New firmware (ver. A105) for only GSA-4163B(Internal 16X Super multi DVD Writer)
Model:GSA-4163B
Ver:A105
