Sorry for the delay.
We have made some tests and it does not depend on the path and source directory. The problem can occur if output DVD files are locked and our program cannot re-write output DVD files. Therefore, if you are playing resulted DVD in DVD player software at the moment when build DVD second time, please close DVD player software. If output dvd folder is opened then you run second build DVD, also please close it to avoid the problem.
If all this does not help, please specify the following details:
1) specify your version of AVS DVD Authoring;
2) specify which settings do you select to build DVD?
3) specify to which folder you build DVD second time? is it the same as the previous?
4) describe your actions step by step after the first build. i.e watch the result, change chapter positions, run build again, etc.
Looking forward to hearing from you.
Regards.
