DVD-R media compatibility and write quality:
In these tests, we will be using the NEC ND-3520A to read back the DVD-R's and the Plextor PX-712A to read back the DVD-RW's.

The KProbe scan shows high PI and high PIF spikes at the end of the disc. The result is not good, but the disc was at least readable.

Perfect reading curve and the KProbe scan is very good.
To sum it up: Overall, the write quality is good on both DVD-R and DVD-RW media.
Head on to next page and read about DVD+R DL compatibility and write quality...

Also another point is that only Lite On was used in tester. I would have liked to see some jitter measurements with a Benq/ NU(Tech) drive to see if the problematics results from C't have something to do with high jitter levels .
I know Benq jitter(uncalibrated measurement) = Not CATS jitter(calibrated measurement !. So should be better !) but still it would have given us some extra data.
