I have been using the Any DVD/ clone DVD for years and from time to time have trouble with some of the movies I try to back-up. The most recent ones have been Happy Feet and the Good Shepard. They appear to copy just fine but once put into a DVD player they are not recognized. It’s almost like the old days of DVD X Copy. I don’t know when the fix will be out for this but until it is I will be copying on DVD+RW’s just so I don’t waist any blanks. I think it’s worth the time to copy twice so I don’t waist another blank.
