I have a fully registered version of NERO, updated to the 5.0.3.8 on a new Win2k build I just installed last night (because it had just been a while). Anyway, I was having the same trouble before I rebuilt too. The problem is that when I try to burn the Solaris Disk 1 or 2 iso, it will chug for a long, long time, and then give a "program error". I have gotten the 3rd cd successfully burnt, but it was only like 200megs vs the 500+ of the other 2 images. I have 2 192M swapfiles on separate drives, and 256 of ram. What could be the problem>?
