Can someone help with a small problem. I've just stared using DVD Lab and have imported a video. When I try to add chapters, I really need to be able to hear the audio as it previews, so I know when to add the chapter point. I realise some programs don't have this feature, or is it like TMpeg Xpress, where I heard that if you don't have a certain codec or something installed it don't preview with sound? Thanks a lot
