Where can I download Internet video recording software to download all web videos?

[Stream Recorder]

None of the Internet video recording programs can download all web videos. You can record almost all Internet videos with screen video capture software (http://all-streaming-media.com/record-video-from-screen/).

See the following thread for more:
The best video stream recorder, stream downloader, stream ripper, stream capture soft

p.s. I suggest you to create a thread with a particular web-site you have problem downloading or recording from.
