Nero Recode-Error

When i try to copy a DVD with nero recode on my BENQ 1655 it get this error messange. Any idea how to fix it.

I checked my ASPI and both nero and systems were fine.

Most probably a badly mastered disc, or a scratched up copy. Try another copy of the disc or wash it with warm soap water and try again. If it still doesnt work, check drive cabling. If problem still persists, it is a remote possiblity that your drive’s optical pickup is failing.

I am assuming that all is well on the software side, in reference to the above.
Hope this helps.
