I got 5 pieces of Maxell 16x DVD+R to try out. MID RICOHJPN R03.
the H20L fw 1.01 refused to let me select beyond 8x, even though the 16x write strat appears in MSCE. So no point testing it.
Tests in SHW-160P6S fw PS0A.
1st burn. HyperTuning/OverSpeed enabled. 16x burn speed selected, but for some shit reason, the real time burn speed in ImgBurn 1.3 never went beyond 6.8x.
2nd burn. HT/OS disabled. 12x burn speed selected. This media is limited to 12x with OverSpeed disabled.
time taken: 5min 58sec, out of which 1 min is spent writing the leadin.
Note: this ISO is only 3.8gb.
