Is this burner junk? I am throwing away 25% of my dvds. I get different errors: Power calibration error Write error Yesterdays I received this error (write error) on 3 of them. I have tried burning at slower rates. (I don't understand this because with previous burners I burned @ 16x with no problems). Under another forum I found a result for googling an error to change IMAPI CD burning COM services under admin tools in the control panel to "disabled". I don't know what that even is, but it didn't help. I changed the firmware yesterday from GLOC to GLOF. I buy my media from bestbuy. Currently I have Fuji, Sony, and Verb. Prior to the firmware update the burner couldn't recognize the Sonys so that is a + since I have about 120 of them still from a sale last year. I burned 10 dvds yesterday and wasted 4 (4/14). With other burners in the past with similar media from Bestbuy I might throw away one in a cake of 50. Any ideas? Did I leave anything out?
