You see I myself reply on alot of forums and help people out well I got a stumper for you guys!!! I have the lg GSA-4040b dvd writer, i use dvdshrink to compress movies and nero burning rom 6.0 to burn them. Nero wont recognize the burner as a 4x burner even without inserting media. When i insert high quality 4x media (maxell, pioneer) it still only lets me burn at 2x. I have upgraded the firmware, reinstalled the drive, reinstalled the software. Anybody got any clue why i cant record at 4x???
