"Cyclic Redundancy Error", what is this?

I recently installed the new version of CloneDVD and AnyDVD and on Die Another Day, Hot chicks, and The Nutty Professor I got this error. Can someone tell me what this error means and how to fix?? Thanks. :slight_smile:

Did you really need to cross post?

No, I posted in this section first then realized that it should be been under cloneDVD. sorry…
