I have purchased a Sony DRU-700A in order to make copies of DVD movies. I use DVD decrypter to rip the movie to hard-disk and dvd2one or dvdshrink in order to make it fit on a DVD-R. I usually select only the movie without any extras. The problem is that although I can play the movie on hard-disk when I burn it, it is no longer playable. It freezes continuasly sometimes in the middle of the movie, sometimes at the end. Does anyone had the same problem and is able to help?
