I just had a strange problem backing up ladder 49. I copied only the main title The burn was sucessful but when I checked it with Nero CD/DVD speed quality check it showed a perfect burn up until the last part of the burn then it went nuts with over 9000 PO failures disc quality of 0.
Chapter 13 is the problem apparently when I tried to paly it on the backup I got a black screen and a lock up until I removed hte disk from the drive. on the original disk chapter 13 is a momentary black screen and then you are kicked to the main menu.
I am guessing that since I didnt preserve menu's this is the reason for the lockup. I tried cutting chapter 13 when I recopied it but it still appears. and the recopied movie plays fine up until chapter 13.
I am using CloneDVD2 2.7.51 and AnyDVD 126.96.36.199
