I think you are having problems because your drive does not support proper EFM encoding (well, you have 1 sheep out of 2 LOL!), and Safe DIsc 2 uses EFM encoding as part of its protection scheme. The best way around it is to use Alcohol 120% (you can download a free demo from
http://www.alcohol-soft.com/) When you get Alcohol 120% go into the preferences, and under "extra emulation" select "bad sectors emulation"
That SHOULD do the trick
(it's easy to be quick when most of what I do at work is surf the web looking for people to help and new things to learn [:p])
