This is from the DVDFab FAQs on their site.
It was my thought this disc might have a "bad" spot on it.
Dirty or scratched.
The "Ignore all the reading errors automatically" may allow the disc to be copied.
Then you will need to preview it to make sure there are no artifacts . Or none so bad you can't live with them.
What does "Error while reading! Please choose what to do? retry, abort, ignore, ignore All" mean and how to fix it ?
There should be some files on original movie disc that can't be open or read, in this case, you can try either of the following:
1. Clean this movie disc and your drive tray first, and then insert the disc in to see if DVDFab can read it successully;
2. Go to the retail shop to change the disc for a new one if it is newly purchased;
3. Open "Common Settings" window, click on "Read", select "Ignore all the reading errors automatically", then try again to see the result;
4. Go to "Common Settings/Pathplayer" setting panel, deactivate pathplayer to copy this DVD again to see if this works.
