I also tried using different websites but they show the same error...
Please help.thanks

You'll just have to stick with the legal way of viewing the videos. Go to YouTube.com.

Unfortunately downloading material off YouTube is illegal (or at the very least in the grey area of the law).

Excuse me,are you saying that YouTube has just forbidden downloading lately??

Many things posted on YouTube are removed daily. So if it possible the downloads you are looking for is not there.

Also not all things posted there can be downloaded and something's are not allowed to be because they are copyrighted

excuse me,are you saying that youtube has just forbidden downloading lately?!!??

If YouTube allowed downloading there would be a download option on YouTube's website. Downloading videos from their website at the very least is a violation of their terms. As mentioned, some videos on there are copyrighted and therefore it is illegal to download those videos too.

Oh no... I just download short fanvids which are allowed and available to download!:) as everyone does it... and I've heard it's because YouTube has made some changes.. I just wanted to know whether I'll be able to download again:)... I just heard that others have such problem while downloading YouTube videos,too... has it happen before?!
Thanks for your answers

How do you know it is allowed with those videos? Did the owners give you permission? If I posted a video on YouTube, you don't have permission to download a permanent copy until I say so. Some people will post links in the description of the video where you can go to purchase the media they have uploaded on YouTube. Unless the owner of the media explicitly says you can, then you have to assume you can't.

There are many Firefox plugins to locally save Youtube videos.
