I am running a p4 2.80ghz with windows xp professional sp2 computer. I have a plextor px-712uf dvd-burner. When viewing my computer without any media in the burnerir reads as a dvd-rw drive. when i insert a blank dvd-r, dvd+r, or a dvd+rw media my computer changes the drive to a cd drive. I am unable to burn a dvd using any of my software programs. The programs i have are plextools, roxio easy cd/dvd creator 6.0, copy2dvd se, 1click dvd copy. I have the latest firmware for the burner installed and still not able to burn a dvd it is reading it as a cd rom or cd burner. can anyone help me i am at wits end here.
