I was surprised when DVD Decrypter showed only a 6~6.5x speed range. The media I was using was "Legacy" which has the Prodisc ID. I ran the Plextools to make sure there was nothing unusual in the drive settings. Everything semed ok. I did use the media check function, and the result was something like, "this media may fail to have optimal characteristic..." Seemingly, I had my answer for why the drive was only burning my 16x media at about 6.5x speed, right? I wasn't sure, so I bought some Verbatim 16x DVD+R, and guess what, I had about the same speed limit. Except, this time, the media check said I have "good media". So is there something wrong with my drive, the firmware, Plextools (v2.23), or perhaps with DVD Decrypter? (btw, DMA is enabled for the hard drive and PX-716SA) Anyone have any suggestions what I can do to unlock the speed potential of the drive?

And have you set up your plextools?

I hadn't thought to look there before for this driver issue. The Nvidia program removed the IDE drivers, while I kept all the other Nvidia chipset drivers. Then I rebooted to Safe Mode and it configured something, so I had to re-boot again into Safe Mode, and Windows 2000 installed the Windows default drivers! Then I ran a driver cleanup utility called "DH DRIVER CLEANER", and re-booted to normal mode. I ran the Plextools Read test, and watched as the speed slowly climbs....6.1, 6.2, ... 7.3, and it flattens....uh-oh, no improvement. I guess I'll one more thing to try: I go into the device manager and make sure DMA is selected for everything. Back to Plextools, and the Read speed hits 7.3 and keeps going up! I burned a DVD+R at a peak speed of 15.9x!! Looks like the problem is solved!
If only Nvidia driver had been more compatible. I wonder why?
