Hi there,
I use also DVD -R for burning, and make the following Steps:
1.) Use DVD-decrypter to copy the DVD to the hard drive,
2.) then I use normally Clone DVD (but there are various other good programms like pinnacle instant write, DVD copy suite....you name it) to burn the movie to DVD. IMPORTANT: burn the DVD at a low speed approximately 2-2,4x, this because to avoid read errors that occur whenn u burn too fast....
Hope I was able to help u if u have further questions write me a pm..
