I think you might have to get your mind round Vegas a bit. there's a "how to" dialogue that opens when Vagas Movie Studio opens. There's a bit on here showing how to capture video. It involves the little picture of a camera on the project media tab.

once the video clips are captured and on disk, you can import them into other projects via the "file, import" option.

Be patient with me; I'm quite new to this too.
