DVDFab v9 no audio

[candiecat]

Is there a reason there is no audio on playback on some copied movies?

More info is needed, are these dvds or blueray disc's.
Is there no audio at all or does it cut off at a certain point.
And what are you playing these movies on ??
If the sound cuts out at a certain point then it is a cinavia issue.
And please post the dvdfab internal log files.
