The burning speeds in Nero are based on the capabilities of your CD-R drive, Nero 5.5.10 allows me to burn at 4x, 8x. 12x, and 16x. My CD-RW drive is a 16x drive, so that makes perfect sense.
FWIW, I think you may have better luck changing the media brand, rather than trying to change the burning speed. I burn my music CD's at 8x and 12x, and they sound fine on any of my CD players.
