Good to know Albert .
I will soon be installing an LG drive .
(Waiting on a SATA controller card for the additional port I need).
I checked my OS which is Vista .
The key above :
doesn't even have NeroToolkit .
The key that has it in HKEY_CURRENT_USER is:
HKEY_CURRENT_USER\Software\Nero\Nero8\Nero Toolkit\DiscSpeed\CD Quality
Blocked is a String value & has only "HL-DT-ST,PLEXTOR" .
I also have this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Ahead\Nero Toolkit\CD Speed\CD Quality
It is set the same way .
Both Nero CD-DVD Speed v 126.96.36.199 & 188.8.131.52 & Nero Disc Speed 184.108.40.206 work with the Samsung .
With Samsung the "Jitter" reading is not available .
All of this is in the thread by mciahel :
I guess I will need to test the LG when I get it installed & see if removing the "HL-DT-ST" works on Vista.
