how to set Nero Burning room speeds? help


I cannot seem to figure out how to set the read and write speeds for burning CDs on my computer. I have Nero Burning software. Does anyone know how to change the settings? My CD copies are unlistenable, presumably because I have read or written too fast.
thanks

Thanks Rives.
Is there any way to set the read speed? I think that might be part of my problem too.
thanks again
One other question: When I check the write speed, it offers me options down to 4x, but no slower. Does it make sense that the writer can go no slower than that?
Check what speed your driver specs for; on most it's written on the front. Go with that. Actually, on older drivers it's often 4x anyway.
