I had the same problem. Since I was in an instructional setting I performed a quick work around. Simply opened video with one click in MovieMaker, then imported it into Studio. What I can't understand is: if of all people, Microsoft can make capturing a video that simple, why can't a product you have to pay for do the same? I don't want to continue using this workaround, so I hope someone tells us the answer.

By the way, I tried several comuters. In addition, in other forums, it was suggested to reinstall software. That didn't help.

Someone help!
