Most of my backup coppies become unreadable and breakup within about 15 minutes of the end of the movie during playback. The ripping and burning goes off without any errors but the end is bad. I am using DVD shrink and decrypter. Sometimes if I use a different DVD player it will play the bad part a little further but still get breakup in the end. Are there any settings that can be adjusted to make a better copy? I have Nero for burning also if that is better. I have re-authored and got same results thinking the DVD was compressed to much but that is not the problem. Any help would be great. Thanks in advance.
