The issue happened because the dvd only has one audio track which is an unspecified language.
The DVD fast five has the same type audio track, for this kind of dvd, our program needs a longer time to analyze the main movie, to solve this issue, since version 4.0, we filter this kind of audio track, that means our program won't list it in the audio track window, you can't see it so you can't select it, and our program won't copy that audio, that's why the copied dvd doesn't have audio.
Don't worry, our next version 4.1.1 will fix this issue and we've finished the beta version, we'll release the official verslion soon.
