Sorry if Im not posting this correctly. This is the first 'post' ive made, ever. I am having trouble backing up some of my movies. Im a teacher and regularly get movies 'stolen' so i cant take my real copies to schools, ever. I have a new 'liteon' with atapi-interface, whatever that means. I have no trouble with data or music using my old clone cd program. I have never had any trouble with cloneDVD2 before either. Now, more than fifty percent of the discs I burn dont. I get an error message saying 'bad write media'.
