Hey guys. I use Nero Vision Express 4 to make and burn my movies and for some reason, certain movies will have the picture and audio out of sync when they are opened in Nero Vision 4. All I really need to do is trim the audio at certain points and make it resync with the video. Now, the 1 million dollar question is... how do you trim just the audio? I already know how to trim/cut out parts of the video.
