I recently installed a Plextor PX-716A. Decrypter was running fine until I installed this new burner. Now it only burns at 1.5X speed. I tried reinstalling my I/O Magix 16X but that also burns at 1.5 X, even when I set it to burn at max speed. I double checked all my setting s and they seem fine. I even got the latest firmware update from Plextor's home page. The system I have is a Dell Dimension 3000, 3GHZ chip speed. I'm baffled and ticked off. Any help would be greatly appreciated. The media I use is what I've always used with no issues, Verbatim DVD-R and +R's 8X.
