Since z-modding my 411s, I've burned 5 discs (all RICOHJPNR01) at 8x with no problem but I noticed one thing in common on all 5 - twice during the burn, I will see the LED go yellow for a second or so, as the drive revs up. Nero shows the drive buffer staying at >80% the whole time. Is it normal to get a yellow light when the burn speed shifts 4-6-8 on the 811s? I've had pretty good kprobe results on all 5 discs and they all played fine in a standalone. Also, there is no visible indication on the discs of where the yellow LED events took place, and the write does not fade toward the outer edge.
