UPDATE: YouTube has reworked their site again in response to this article. They absolutely hate us. If you get an error when trying to download a YouTube video, please try some of the plug-ins and scripts listed in step #3.
YouTube.com is a great resource. Not many sites allows users to freely upload, view, and share video clips like YouTube does. YouTube even lets users easily post videos on their blogs and personal web sites. But because anyone can upload a video clip on YouTube, copyright violations are rampant.
In an effort to prevent the widespread distribution of illegal copied video files, YouTube encodes its video files in the Adobe Flash format, which prevents viewers from downloading files and making digital copies.
Here’s a step-by-step tutorial on how to rip video files off YouTube.com and convert them for Apple TV, iPod Video, iTunes and iPhone. This trick will work on Mac or PC using Firefox or Internet Explorer.
