I got the following problem: i recently downloaded a film with extension .avi. i extracted the audio with goldwave and get an archive .wav. my problem start when i gonna join the .avi and .wav with tmpgenc; some parts of film what i created, dont get sound ( the actor talk but his voice doesnt appear in some parts). i think maybe be why the film i downloaded is remastered with ac3 but i dont know how i can fix it.
If anybody can help me, please.

Thanks in advance.

PS: sorry if my speaking english isn't as good, my first language is spanish
