I am not sure about what you mean on booksetting. I have only used the DVD burn function about 2 or 3 times so far and now it won't read or write dvdr. Some of the dvdr discs I have tried were movies (that I had been able to view before) but what I was last trying to do was burn a dvd data disc using ROXIO. One strange thing that will happen is that when I put a dvdr (blank or one that has a movie or data on it) into the drive the icon in Windows Explorer will go from saying "DVD-RAM drive (E)" to "CDR drive (E)". Does that mean anything special? BTW I have Window XP OS.
