Video "Capture" software?

[::::BASSIST::::]

What software might I use to save a video that is not 'officially' downloadable?

For example, if there is a video on youtube, how can I save it om my harddrive for later viewing? (Yes I know that you can 'favourite' vids on youtube... but it might get deleted..... just using youtube as an example)

There's a freeware program called "Camstudio" that works pretty well. Takes up a fair amount of resources when running, though.

I haven't used this, but I found reference to it on a pretty reliable tech blog. (For Youtube specifically)

If you're talking about youtube specifically then just use youtube downloader: http://youtubedownload.altervista.org/
