Hi I bought a 16x dvd burner, the benq one a few weeks ago hoping that i would be able to burn dvds faster. Then I read here that people onlny burn at 4x? Why would they have a 8x or higher mode if it caused that many errors? I guess I dont understand why they would already have many 16x drives out when the best burn is at 4x, just doesn't make much sense to me. Any feedback would be appreciated.
