Using the Movie Studio Capture software my 39 minute video is captured in 89 single clips. How do I set the capture function so I only have one clip to render and work with when I make the DVD?
Well, you could just disable the scene break function in the preferences in your capture window.
But, since you've already captured all your files, it's likely MS assigned numerically sequentially names to your clips -- so just select them all the pull them to the timeline. There's a pretty good chance they lay onto the timeline in the same order they were captured!
