I just installed the Plextor PX-716A, and upgraded the firmware to 1.08. I am burning with Nero 6 Ultra, latest update (22.214.171.124) with Windows XP. I have tried burning a full 4.7GB Sony 8X DVD-R, and it won’t burn faster than 2X. Nero SAYS it is burning at 8X, and actually has 8X in the dropdown box, but it takes almost 30 minutes to burn a full DVD-R, so I know it is burning at 2X. In fact, I also have a Toshiba 4X DVD-R burner (only -R, not +/-R), and it burns the Sony 8X DVD-Rs at 4X. Thus, I have the ironic situation where my 4X DVD-R burner is faster than the 16X Plextor!
How can I get the Plextor to burn at the maximum speed of the media?
