I recently hooked my NEC 2500a DVD writer up to a promise ultra66 pci controller and I've had nothing but problems with it. DVD Decrypter hangs on "getting book type" when ever I select the NEC (but works fine with my other 2 optical drives).
Also when I try to burn with the drive using Nero it has buffer underun issues if I select any speed over 2.4x. The weird thing is when I do a transfer rate test using a data DVD and Nero tool kit the drive is able to read at up to 8x. but running Nero infotool cause the whole systemt to reboot.
At first I thought DMA was not enabled but it clearly states that it is on bootup. I've tried everything I can think of, I've updated both the bios and the drivers of the controller card, I've even installed Adaptec winaspi but nothing seems to make a difference. Any help would be greatly appreciated.
