I can’t believe they actually released new firmware for this drive, I got fed up with the seemingly “final” firmware over a year ago and ditched mine. Just wondering if anyone could test the burn quality on TY T02 code media as US0Q sucked on these discs. Results for Sony D11 (which was even worse by a factor of 2 to 3 times) or Optodisc OR8 would also be appreciated. My prior scan data is from a BenQ DW1620 B7V9 so results from a drive of this type would be ideal.
In case anyone has one of these drives, they absolutely love CMC AE1 DVD-R 8x media. It’s the only media (of the 8 types I tested) that actually burned anywhere near the capabilities of the discs as compared to my other (many) burners. Surprisingly, the results for this media actually beat drives like my ND-3500A 2.1A, DVR-109 1.58, 4120B A117, and 4163B A103 in total PIF counts. Completely out of character performance for the general burn quality of this drive, but at least there’s something that works well. Overall this is a pretty lame drive, so I hope this firmware seriously improves it as Liteon seems to be making some headway with their more recent products.

It’s good to see that they haven’t completely forgotten about the 2S (mind you, most other manufacturers haven’t released any firmwares for their 8x drives since 2004). What I can’t believe is that they released US0S without releasing VS0H (or whatever the next VS0 firmware is called). 
Since LiteOn stopped maintaining a separate development line for the 812S firmwares a while ago and instead used stripped-down 832S firmwares instead, I’m surprised that they didn’t release anything for the 832S since a newer 812S firmware must mean that they also have a newer 832S firmware to have based this newer 812S firmware off of. Maybe if someone asked them nicely…

Well, I flashed my friend’s drive tonight and burned a Nero test disc on it using media that I previously tested on it–and the results are actually worse. Nasty escalation of PIF’s in the 6x zone on this media, and PIE’s are elevated by about a factor of 15 over burns on a drive like the DVR-109 1.57. Ah well it’s not like I expect that much from Liteon anyway but at least it gives me more to shake my head at. I analyzed the same disc on the Liteon itself after burning it and it claimed the PIE rate was under 5 and the PIF rate was under 0.20, with a couple large single PIF spikes knocking the quality score down to 38. This is exactly why I stopped using Liteons for quality scanning as half of the time the results are BS.

The results for the burn with firmware US0Q were 39.89 / 1.14 / 10.83% averages and a quality score of 93. Total PIFs were about 1/3 of this burn done on US0S. Unfortunately I did not save a graph of that analysis. I did note that on that burn the PIE level generally escalated in the 8x zone compared to the other ones. Apparently their latest stategy produces quite a bit different results.

I’m having shocking results with US0S, was using US0J and getting 50-60~ PI averages on ProdiscF01, with US0S i’m getting 300~ !!!
I think it’s about time for me to crossflash
