YouTube has begun adding a 'Click to Download' link to some of its video content.
According to Lessig, this link is being added to "content that aspires to be consistent with principles of open government." They have been told that it will be offered more generally in the future.
Why even bother with all of those sites?
Realplayer is free and allows you to download videos from any site.
Even the ones that those download sites don't work with, or charge money for like xtube.
Now you can happily download all the boob action you want for free. ;)
