It's your discovery, good job!

Hello. for those that want and exact backup of the disc do this:(this will play the previews, etc) open any dvd last version open the disc via DVD Shrink and copy to the hard drive , check the audio video ts folder option let it copy takes about 30 minutes now CLOSE any dvd (important not sure why but it will not work otherwise)open clone dvd , write existing data option and select the folder where you stored it. write to disc once its complete insert into dvd player.you should get the sony splash screen first , if so you are done and it worked . Wow this 1 was a challenge to figure out.
