Writing speed in Nero 7.3 & 7.x

Hello everybody. I,ve just registered. And I’m very pleased in taking part in such usefull community.

I,m going bananas trying to set the writing speed lower than 8x in CD Audio burning: Nero insists in setting it to 8x even if i choose 4x speed. It doesn’t matter if the “multiple recorders support” is selected or not. I tryed to edit the registry: (HKEY_CURRENT_USER\Software…\recorder speed )
I tryed values 0 & 1. Nothing happened.

Any help?

Thank you.
