I can report I have had no problems using the AnyDVD & CloneDVD2 combination to burn movies. The problem you are reporting normally occurs when your burner doesn't like the media you are using.
I would also make sure that your DVD burner has the lastest firmware installed.
To find out what media you are using download something like DVDInfo Pro or VSO Inspector.
There is also a CloneDVD2 forum, where a mod might kindly move your post to.
