I finally received my 50 pack of RITEK G04 "silver-matt" and cant burn with them at all. I keep getting a power calibration error whether I use Nero Or Decrypter. I updated to the latest firmware for my Optorite DD0401 "160E" and also re-installed my ASPI layer to no avail. Finally after trying a few of them I inserted one of the last "cheap" HP DVD+R's I have and it burned with no problem. I must mention that I’ve burned DVD-R media before with no problems. The purchase was from Shop4Tech. DVDInfoPro say's that it is indeed RITEKG04 but I'm ready to send it all back. I had tried to purchase from SuperMediaStore but they no longer ship to APO addresses. If I'm missing something any help would be most appreciated. Running Win2000-SP4 with 1GHz Intel 768 ram.
