I am just in the process of burning a disk using Nero ver. 7.5. Pretty 
old by standards, but it works for me. I was fooling around with the 
normalization and discovered that there are two methods possible. First 
is RMS (Root Mean Square), which increases the average volume by a given 
percentage. The second uses percent of maximum. Using RMS would mean 
that clipping is still possible. Maximum would prevent this. I also 
discovered that normalization, though it can be set on for all tracks on 
the main screen, must be set individually for type and value. To set 
them all at the same time, click on the first one, hold down the shift 
key and click on the last one to select them all, right click, 
properties, filters tab, make your selection, check the normalize box, 
then click OK.
I have had this program on my computer for a long time and never 
realized this.
