HI,
i have downloaded and installed the latest firmware for the plextor.
i think this allows the plextor to read & write dvd-r d/l discs,
correct me if i am wrong,
in plextools which i am using the latest version, under feature
it does not show dvd-r support, also mount rainer is showing absent.
firmware 103 showed it used the mount rainer facility.
dell.
