In Roxio Creator Special Edition 2011, how do you make the video input go full screen?

There's a window that shows what's going on, and within it, I can see what on the video output, but that part of the window is tiny 320x240. I KNOW the resolution for the device I'm using is a lot higher [probably at least 640x480,] but I'm not entirely sure; this is a brand new DVD/VCR combo.
