Yamaha 8424e question

My yamaha CRW8424E (firmware 1.0j) only write at 4x
i have the same problem with my sony 16x driv.
I have nero on my computers. anybody knows what’s wrong?

You can’t select the 8x or do the burns fail at this speed?!

i can’t select 8x or 16x with my sony
4x max

I think you use CD-R/RWs which can be written faster than 4x?
Nero asks the recorder for the max allowed writespeed. This depends very often from the CD-R/RW inserted. Yamaha recorders uses the Optimum Write Speed Control to detect the allowed write speed. If your recorder supports this, then you can disable it under Recorder -> Choose Recorder -> More.
Another reason could be, that there is a on old(?) driver of a packet writing software installed which modifies the result the recorder delivers.
A way to fix this, is to modify the detection method of the allowed write speeds.
Please change the value of the following key:
[HKEY_CURRENT_USER\Software\ahead\Nero - Burning Rom\Recorder]
new value: dword:00000001
