Since it's against Youtube's Terms of Service to download their videos (see below), it's therefore against our Forum Policies to discuss such items..

5. Your Use of Content on the Site
"A. The content on the YouTube Website, except all User Submissions (as defined below), including without limitation, the text, software, scripts, graphics, photos, sounds, music, videos, interactive features and the like ("Content") and the trademarks, service marks and logos contained therein ("Marks"), are owned by or licensed to YouTube, subject to copyright and other intellectual property rights under the law. Content on the Website is provided to you AS IS for your information and personal use only and may not be downloaded, copied, reproduced, distributed, transmitted, broadcast, displayed, sold, licensed, or otherwise exploited for any other purposes whatsoever without the prior written consent of the respective owners. YouTube reserves all rights not expressly granted in and to the Website and the Content.

B. You may access User Submissions for your information and personal use solely as intended through the provided functionality of the YouTube Website. You shall not copy or download any User Submission unless you see a ?download? or similar link displayed by YouTube on the YouTube Website for that User Submission.

Primarily, Youtube videos aren't of high quality in the first place, (The size requirements for high quality videos is beyond any site's capacity), and second, any programs/sites which offer copying options don't provide high quality tools.. So, if you actually have permission from the owner of the video, why not ask the owner for a copy?.. You'll get the best quality copy available.

Locking this thread.

Hope this helps.
