But it is possible to burn DVD-RW (Verbatim max 2x) ?!?
OK here the scans (with LiteOn SOHW-1693s):
Media is DVD+RW Verbatim MKMA02 (max. 4x)
First scan burned with NEC-2500A at 2x (2x or 4x writespeed selectable)
Second scan burned with LiteOn SOHW-1693s at 4x (only 4x writespeed selectable)
The Quality-Score is the same (?), but the summary PI-rate is much higher at the DVD+RW burned at 4x with the LiteOn.
The third pic shows the bottom side of a DVD+RW burned with the LiteOn. It shows “waves”. The NEC-burns (2x) are OK.
These “waves” did not disappear after using a full format.
I don’t have a drive to rezero the full media.
