Using the alpha firmware that allows RICOHJPNR01 to be burnt as RICOHJPNR02 (up to 12x speed):

This is a disk burnt at 8x speed. It seems well burnt, however the liteon 166s quality scan is somewhat bit worse (2.5 times works) then my 4x LG burns of these disks. It plays fine in a playstation, and reads pefectly in all the drives I tested.

At this speed, RICOHJPNR01 is perfectly usable. The Pioneer 116 reports an error because it wasn't able to correctly determine the disk size. I was suprised I was able to get a relitively nice read at 16 speed on the liteon drive. Most normally burnt media, let alone oversped, don't do this well, so thats a bonus.

PS. I know that the 166s is a finiky drive and not great for scanning. But it is quite critical of anything my LG burns, and that is a good thing for comparing burn quality. I might do a few scans when I (if I ever) get my benq 1620 back from RMA.
