You can enable Pioneer scanning in DiscSpeed with a small registry edit:
Go to "HKCU\Software\Nero\Nero 9\Nero Toolkit\Nero DiscSpeed\CD Quality" and remove PIONEER from the "Blocked" entry.
After doing that, you should be able to scan with the Disc Quality tab. Keep in mind that you may wish to go to Settings - [Advanced] in the Disc Quality tab and then move the Slider to "Speed" and change from 8ECC to 1ECC scanning.
Pioneers may not be the most accurate scanners (at least compared to LiteOn or recent Optiarcs), but they are good enough to get a quick glance at the disc quality.
