Your message left me a little puzzled. You ask about uploading and then you tell that you have difficulties downloading. If I understand correctly, you're trying to get the historical movies from a source like Youtube and save them into your computer. That's downloading. Uploading would be the opposite, transferring material from your computer to a server and service for everyone to see, like uploading a video into Youtube.
Now that we've got the terminology issue sorted, there are many tools available to download video material from an Internet source. Google for "flash video capture" and you'll find plenty of tools and advice for grabbing Flash Player based videos. If the site you're downloading from doesn't use flash, then a search for "[site name] video capture" might give you the answer.
