I've been using dvd 43, dvd shrink, and Roxio 6 to make backup copies of my dvds. I never had any troubles until a week ago. Sony, over the years, has been infamous for its restrictive attitudes on its products. A lot of their CD/DVD players won't even play burned items; be careful. I'll try the latest Anydvd/clonedvd along with what I am already using. Thanks for the info--good looking out.
