This is my first try at Vegas 6.0 - not very computer savvy - old - but willing to try this. I downloaded a video off my digital movie camera, got it into Vegas, on the track that says "video", and can play it and preview in the window in the bottom left of screen. But none of the dialog plays. I have clicked and unclicked "mute" button - nothing. What am I doing wrong. Thanks in advance. MK
