Hey now. I purchased Vegas Movie Studio Platinum 9.0. I can't figure how to replace the audio on a video. I load up the video (in my case an AVI) Then load the audio. I get them synced up and mute the audio on the video and then render to AVI. All I get is a black screen though with nothing. Help. ;D

Make sure the video track header was not muted.
