i have an 8x dvd burner that only goes at about 1.38x (used Nero's "test drive" feature). i also did a dvd burn that took about an hour. i thought it would take less than 10 minutes. even regular cd burning takes a long time (over 10 minutes when it's supposed to write at 40x). my drive is an "Exact" brand. didn't come with any drivers. cant find them online either. my comp detects it as a generic 8x burner. how can i fix this!? i want 8x speeds! the drive is in secondary master.
