It looks like maxpreps.com has a current list of Bentworth High School's football games with the option to watch either previews or full games. I'm not sure if the site is affiliated in anyway with CBS, but it looks like the most comprehensive source. You can also find highlights and some partial games on Youtube.
If these links don't provide what you're looking for, I recommend calling the Bentworth Athletics Department at 724-239-5911.
Best of luck finding those videos! Enjoy the rest of your weekend!
