Burning CDS

[therocci]

Okay I need help, I have Cakewalk Guitar tracks, I bought a CDRW 4x 4x 24x I bought Nero 5.0 to burn CDS. Now when I listen to my songs on Nero they sound just like I mixed them on Cakewalk. So I burn them on the cd and when I play back the CD they have this high tweaky pitch throughout the whole song , I am getting ready to throw my computer out the window can anyone help??????????
