Nice review, Jan.

I wonder if Philips mentions the SolidBurn and OverSpeed options anywhere in the documentation with this drive.

Reason I ask is that I had just bought a Philips SPD6000 (new LS model). As far as I could tell from the information on this forum, that should have been a BenQ 1655 rebadge. However, there was no mention of SB or OS and the drive was not supported by QSuite 2.1. In the end, my drive turned out to be defective (it produced two coasters out of three burns, then stopped recognizing any media I fed it, so I returned the drive and bought a BenQ 1655 instead). Maybe it was not even a BenQ rebadge at all.
Anyway, I could not find any info about SolidBurn or OverSpeed (or any utility to set it) with the SPD6000, so I wonder if this is the case with the DVDR1660.
