I do not know, how it works with 1.06, but I've tested NEC's reading capabilities with my 5-6 years old disks, firmware 1.08, with scratches and damages... Really bad disks! And DVD-Reader Toshiba SD-M1612 does not read this disks, Teac 540e CD-Reader reads with problems, like my NEC 2500a. My opinion - NEC is a GOOD reader, for me. Not EXCELLENT, because I am reading this forum and, maybe, I have good quality drive. Personally I have EXCELLENT RESULTS with reading.
PS Maybe, reading quality depends on PSU? I have good HPC 420W PSU.
