To anyone interested to know the solution to this problem, I still do not know. BUT the support at Gateway (which is rather good) sent me a driver to install. I did, and that helped a lot. Along with adjusting the settings on my graphics card, my video is now acceptable. I am currently working on my project, and will pursue other options at a later time. The video is still not perfect, but it will do for now.
In the meantime, if you come up with any genius ideas as to what could be causing the fuzziness/flickering still present, I am open to trying anything!
Thank you to everyone who offered their help. I greatly appreciated it!
