I picked up a DRW-3S163 from office Max this past November for 40 bucks. When I finally started burning DVDs, I crossflashed the burner to a Lite On SOHW-1633S with firmware BS41. I burned a few discs like that, but I got curious about the quality of the burns.
For that reason, I found out about kprobe and did some testing. The errors looked pretty rough from what I could tell. I started reading up on the drive and its related family, and noticed that everyone was talking about crassflashing to a 1653S, now, because of its new firmware. I tried that tonight.
I've done additional testing on a new burn with the CS0K firmware. The PI errors are considerably lower now, 18.54 compared to 54.84. At the same time, the PIF is higher now--1.81 compared to .60. Can anyone shed any light as to why this would be happening? I'm using DVD-R 4X TYG01 media from supermediastore, and I am burning with Nero 220.127.116.11, if that helps the completeness of the information.
I've also attached the two kprobe scans with the different firmware. Many thanks for any information you all can help with.
