Just installed a Pioneer A08XL and archived 2 DVD's the first was to a Verbatim +R DL rated at x2.4 according to nero this was burnt at x4 the next was to a TDK (ricohjpn r02) rated at x8 the burn took place at x12
I'm using the version 1.10 firmware on the drive my A07 would only every burn at the rated speed of the disk so if the A08 is burning by some other means I'm impressed.
Yes both disks are without errors and given the actual burn time I'd say nero was reporting the correct speeds.
