The spindle of +16x playo that I picked up were also MCC-004 and made in china.
Top disc successfully burned,but no drive would recognize it.
2nd disc burned at 8x failed during the burn at the 90% mark.
There was a white label saying “Playo Passport” inbetween both those discs.
A disc in the middle scored 95 on my benq 1620.
The 3rd disc on top also scored a 95 on that 1620.
I just tested disc #4 on my Benq 1650A at 4x.
Archiving with these? Not me,but great for passing around.
