I had the opportunity to briefly inspect both drives before purchasing and I choose the DVR-S20BK as it comes in a retail package with Nero 10 Essentials. The DVR-220LBK is a bulk drive, but additionally has labelflash. The DVR-S20BK has the Pioneer name printed on the tray door, while the DVR-220LBK does not. I think that the DVR-S20BK is probably using a MediaTek chipset as it has a memory buffer of 1.5MBytes, but this is something that needs confirmation. The drive came with firmware 1.01 and was made in October 2012 in China.
