After digging through your other threads, you seem to provide different amounts of information in each thread. So let's start by finding out exactly what is going on.
1/ What are you doing, exactly. I mean, I know you're trying to copy some discs, but what are the exact steps that you are taking?
2/ What is the exact error message are you getting? Can you get a log of this error? If not, could you get the exact error code and the exact text of the error?
3/ Depending on what the problem is (we're not sure right now), some background technical information would be helpful. Some tips on what kind of technical information would be useful to provide are outlined in point #4 here.
