And by the way I've forgot to mention, you can download even those restricted videos without to login with a Youtube account.
Badass, i was getting fed up with hooktube. because it wont let you do that.
Sadly it looks as if Youtube-dl.exe has stopped working.
Are there any other alternatives?
Google changes around stuff on youtube more times than needed, and to keep up with the changes youtudbe-dl needs to be updated ever so often. And as with >>4764
whenever youtube-dl shows an error an update usually solves it.
