Have you ever looked for public domain videos or music files? Well if you have I found a pretty good site to get them from.
The Internet Archive has tons of Movies, TV shows, TV commercials, music and audio for you to choose from most of them being public domain.
Some examples are The Beverly Hillbillies, Petticoat Junction, Andy Griffith Show, The night of the living dead and Hercules (Movie).
The Internet Archive is basically a digital library of anything that can be in digital form and best of all it is free.
