I’ve used my 4160B a long time since I bought it last year.
It works properly with Yuden 4x/8x & MKM 8x/16x DVD+R but has big problem with my old MKM Metal AZO CD-R …
The write speed is only 16x with my NERO 22.214.171.124
I believe the system is OK 'cause I can write a Verbatim CD-RW at 24x
And the CD-Rs are for sure no fake 'cause I can write it at 48x with my old Lite-on CD-RW writer … and even in 4160B the NERO can recognize the disc label as Mitsubishi Chemical Inc.
Today I updated my 4160B with A04 firmware but the problem is still the same. What can I do with my hundreds of old CD-R stock??
