seems you discovered some new feature
Even Google doesn’t show any further information.
At the moment, I’d guess this feature is supported with Nero only.
But the results are very good
It seems that even the local Samsung support center is not fully aware of this feature. They told me that the “P” version came a couple of months later that the original release of the 203 series carrying all previous changes and improvements in the hardware. My drive shows November 2007 as production date with firmware SB00. In May 2008 a new firmware SB001 was released to improve CD-R burning with some media. No other firmware was released for the “P” versions since then. I must say that I am surprised (in a good way) with it’s burning capabilities, especially for DVDs (cheap media included). I will try to post some more scans this coming week.
I don’t know if any of the guys here who bought a drive from the 223 series are able to use this feature…
