I have two dvd burners: SON DRX530UL & SON DRX710UL... I use DVDXCopy Platinum... and I received Nero 6 with my SON DRX710UL and would like to use it to copy my burned DVDs as DVDXCopy does not allow...I need to use one of the burners as a source and one as a burner... i don't know which is better since the dvd+r and dvd-r media I have is only 8x max compatible. When I try to copy in Nero, it begins the process and then after 30 sec it says 'power calibration error' and calls my dvd burner a SON DRU-530A... If anyone can help, explain, or give me an answer, I would be greatly appreciative!!! THANKS!!!
