This same thing has happended to me before and is happening again. This isn't working for me this time, but when it happened to me previously I restore system to a previous date before installing the newest version of Itunes. This worked. Then try installing 2.0 again. Hope this helps.
Okay. here's what worked for me this time. Try reducing the speed at which the CD's are burned. Got to Edit, prefrences, advanced, burning and change to a slower speed 8x worked for me but I'll try a faster speed later. This is very slow. But the good news is it worked!
