Well, the problem may be the audio ripper, or the audio source.
THe other problem, may be the translator.
Is all of the audio out of sync for the language?
If so, then open the file in Audacity, and add some space to it.
Open the file in audacity, and guess the number of seconds it takes for the action to be performed.
Then, click Generate and Silence. Input the amount of seconds/minutes.
Open the audio that is in sync with the video under the audio clip you need to modify, so you can see how close you are to being correct.
That way, you can modify the tracks to be nearly exact in length.
If one audio track is before the video, highlight it and select the 'Format specific Options' tab.
If you think the audio is leading the video by half a second, insert 500 (milliseconds) in the 'Delay' box and mux.
