I've a LiteON 1633S@1653S with CS02 firmware modded by Omnipatcher and a Nec 3500AG with lastest Quikee V3 beta 3 firmware.
The trouble is that... the LiteON burn all DVDs at certified speed, for example a RICOHJPN R02 8x certified is burned at 8x if I try to modify the speed (by Omnipathcer) to 12x or 16, the resulting DVD is DAMAGED.
Also Nec with modded firmware automatically recognizes almost 8x DVDs+R at 16X. for example
RICOHJPN R02 8x --> 16x
MBIPG101 R03 4x --> 12x
MCC 003 8x --> 12x
And the DVDs where burn PERFECTLY without bad sectors etc.
I was a LiteOn's fan before this day. :sad:
