I'm new to the whole DVD copying thing and have just started using Elby's Clone DVD and Slysoft's Any DVD. What tends to happen is that on some discs the copying is perfect, with both picture and sound being 100%, while on others the sound breaks up in various places throughout the disc, making it impossible to watch. I don't store the information on my computer, I simply copy the original DVD straight onto a blank DVD+R disc. Any suggestions why this happens and what I need to do to resolve it would be very much appreciated. Andy.
