Ulead Video Studio 11 shows error

I am using Ulead Video Studio 11 which is a video and photo editor, animation and DVD authoring tool. I installed it on Windows Vista but I can’t capture a video because I only hear sound but I can’t see any picture. And when I try to end the capture or stop it I get the error message below. It says Capture failed so can anyone tell me how to resolve this.

Error message:
Capturing failed. The file created is corrupt and unusable. It will be automatically deleted.
