Can you copy a NAVI disc?

If it is copy protected, I doubt it's something that CloneCD or Alcohol 120% couldn't get around. Last I heard, Safedisc3 had not been broken but I wouldnt think the navi discs are protected by that. Nearly all other copy protection schemes can be circumvented by the above programs.

Hmmm after posting that I realized that the navi discs you're talking about are most likely DVD's. So you'd want to use CloneDVD rather than CloneCD, but Alcohol 120% can copy CD's and DVD's
