I have got Benq DW1670 rewriter, upgraded firmware for latest version 103.
When I run Nero CD-DVD Speed 4.60 “Disc Quality” test with DVD media - it fails reporting “drive does not support this function”. Tech support suggested to write media on this burner and test again. I did it but result was the same.
At the same time “Disc Quality” runs successfully for CD media regardless on device it was burnt with.
BenQ tech support cannot give any intelligible answer. Can anybody help please. I have bought Benq because it was announced that all models support PI/PO error reporting. My purpose is to check my DVD library - to recognise disks that still readable but contain abnormal amount of PIF/PIE.
