Couldn't find more appropriate forum for such question...
Is it really impossible to determine manufacturer of an already-burned CD? Both KProbe and DVDInfoPro, both on Plextor and Sony drives I own, say that I give pressed disks.
Maybe that was because I always burn CD's in "Disk at Once" mode, and finalize them?
And more general question - as far as I know, for DVDs there are different codes for different manufacturers, but that's not the case with CDs. How then are they identified? And what are those A+/A-?
