Umm, the Kprobe tests done in all recent reviews of DVD Burners have been done using the Lite-On LDW-411S.
Read the review properly...
To quote from the NEC ND-2500A review...
"So we recommend using a DVD-Writer from Lite-On, in this test we use a Lite-On LDW-411S DVD-Writer,......."
They tested the media burnt by the NEC ND-2500A in the Lite-On LDW-411S.
It's a Lite-On only utility.
Everyone is doing Quality tests with this, because it's basically the best way out there, to determine the write quality of a burner on a particular burn. It's not perfect, but it does give a very good idea on how good each burner can burn to different media at different speeds.
If you don't have a Lite-On DVD burner, then your out of luck.
You can use a DVD reader or Combo drive, but the results arn't comparible to a DVD burner. Again, Quote from the NEC ND-2500A review..
"as already said; remember that scans done with a Lite-On DVD-ROM or Lite-On combo drive canâ€™t be compared with the results obtained with a Lite-On DVD-Writer."
Based on my tests, DVD-ROM/Combo drives can't be relied on to give anywhere near accurate results, and are worthless/meaningless.
