							Hi,
 When I attempt to burn Audio CD's using Nero the write process will fail near the end, usually once it's at least 85% finished. The problem originally occured when I installed Nero 7 Ultra, I tried to uninstall and reinstall Nero 6 but the problem still seems to be there.
 
 I have read a few other threads containing similar problems... but I was unable to find a solution. I'm unsure of how to update Firmware or where to locate updates. I have also tried to lower write speeds.
 
 Any help would be appreciated!
