nero6 suspected burning bug

i noticed thats if you do other stuff like surf or play a game when you
burn a cd it creates error but when you dont do anytin while its burning
it burns fine. is this normal? or is there a problem somewere.

 

Yes, it's called buffer underrun. Most new burners have little memory
chips in them to compensate for this. But that only works to a point.
If you try to run a system intensive game while burning a disk I don't
care what you try you're going to get a coaster.
