Nec 2510 does not support reporting PI/PIF/PO/POF in a known way.
It can't be used with Disc Quality Scan in CD DVD Speed.
The same applies to Pioneer drives.
Back to topic....
I don't personally think that the 3s series drives produce very good results based on all the prelim results. Of course, as with any LiteOn, that might improve slightly with new firmware. Still, I don't think they offer viable competitoin against LG, Nec and BenQ, imho. The quality just isn't there with the 3s LiteOns.
However, the smart money is (imho) on the 5s series drives rumouredly coming next as it's completely a new chipset, hopefully devoid of the Mediatek supposed performance bugs.
But as always, we'll see when we'll see. There is always something new around the corner.
