found that it was the 12x burns not letting the rp56 read the disks. @4x it is flawless and @8x usually not an issue, some glitching but not bad at all, very little in fact
it was my understanding from cdfreaks site that the liteons dont like -r media?
using fw patched bs0s 1633s liteon patched from a 1613s sl to 1633s dl
and actually the kpobe results are 4x,8x and 12x not 8x, 4x, and 12x as previously posted
