I recenty purchased CloneDVD2 from slysoft and am able to burn most DVD's. I am having problems with some of the other ones and cannot figure out why. I go through the whole process but before I burn them completely, it says that there is a missing track that is needed to complete. This problem only occurs with movies such as the Da Vinci Code and other newer DVD's. Is there a problem with my program or do I need to upgrade to AnyDVD?
