I have decided to back up all the dvds and using the guides i have had great success until i tried Pirates of the Carribean. I've used the guide for dvd9 to dvd5 using dvd decrypter, dvd2one and then nero, this all works perfectly until playing. For some reason the disk skips forward each chapter with about a 2 second delay this is only on one machine ( Sony DVP-NS305 ). Both the X-box and my Technika DVD1020 play the disk perfectly. Would it be worth me re-authoring using TMPGenc DVD Author using the VOBS or is there something glaringly obvious that i've missed. Any ideas would be appreciated as im a bit puzzled.
