Downloading videos off Youtube is NOT illegal, it is a breach of contract as a violation of the terms of service, but there is nothing criminal about it.
I'd just like to add that YouTube does not actually stream video to their clients. Every time you watch a video on YouTube, it is downloaded into your browser's cache and then played back (playback occurs while it's downloading in most cases).
This means you don't need any fancy tools for downloading a YouTube video, because this happens automatically when you watch one. Now, if you want to keep the video you watched, you just need to find out where your browser stored it on the hard drive. This can be done by performing a search for any files created in the time frame that playback occurred. You can narrow down your search by telling Windows to ignore files that are less than 1MB in size. You'll pull up a small list of files with random names. Look for the largest one and copy it to your desktop. Rename it to filename.flv and try to play it (note that you'll need a proper codec installed to play .flv files directly). If it doesn't play, choose the next likely candidate from your list and repeat the process. Before you know it, you'll be able to spot the videos easily.
Note that the videos are only stored temporarily, so don't watch any other videos until you save the one you just watched. Also, don't close your browser because it may flush the cache depending on your settings.
Sounds easier than it is,I'd bet
Honestly, Youtube is a large cesspool of copyright infringement within itself. You have people who record themselves playing video games and posting them and getting monetized from it with youtube partners. Then you have the small people who simply upload some songs so others may listen to them and they get taken down within a few months. Maybe even days! It's sickening really.
It's just a problem with Copy right. It youtube's decision to protect the Intelligent property of the uploader's
I have stumbled across this topic and decided to step in, because I, too, am upset that I cannot download videos through RealPlayer anymore. I noticed the replies to this topic are mainly talking about Copyright issues, and I thought I could give some input.
What I think, is that YouTube could add a option for the people uploading videos to allow/disallow video downloads, or something that automatically does so based on copyright information for the video or channel. Also, downloaded videos could include some protective measures to avoid people re-uploading said videos (to any site, really), to avoid confusion between who's video is who's. I believe this could solve some issues with people trying to download videos to watch later, or maybe keep for personal use.
