Top fixes for any burn issue in iTUnes is...
1) Goto the PC makers site and manually look for updates for your PC, especailly BIOs and chipset/IDE controller updates and firmware updates for the CD ROM (If it came with your PC when you bought it)
2) Slow the burn speed from "Max" to something like 12x 8x or 4x. you do this by going to edit>preferences>advanced tab>burn sub tab
3) Try a different brand or type of Blank CD
You can also goto Help>run CD diagnostic and copy/paste the whole report here (So we can help you) and on apples site here (So they recieve feedback about the issue and help them build a better CD burn engine in future versions of iTunes)
