Easy Way to Download YouTube 3D Videos (September 2013 Update)
Watch 3D Videos on Youtube
When watching a 3D video on YouTube, the settings icon (the 'gear' icon in the bottom right corner) presents a 3D On/Off Switch. Be sure it is in the "On" position, then select your preferred options. Without special hardware, you may select "Full Color" and "Red/Cyan" to display the video in anaglyph. 3D will only need a inexpensive pair of red/blue glasses.

Best Video Downloader for Mozilla Firefox, Internet Explorer or Chrome
If you use one of the three most popular browsers, you may download and use the free "Best Video downloader" application. This Mac and PC add-on has been updated recently with several bug corrections, making it better than ever.
Description by the author: the fastest YouTube downloader add-on available online! Download YouTube videos as 128kb MP3s up to 30x faster than any of the competing downloaders.

Caution: Be careful during the install procedure as the installation script will propose to install various uninteresting toolbars and add-ons; cancel those and just install the main script.
Another Stand-alone Youtube Downloader application
Alternative solution: You may download the stand-alone (and free!) "YouTube Downloader HD". The last version known today (version 2.9.6) weights only 4.5 Mbytes. Usable on any Windows 2000/ XP/ 2003/ Vista/ Seven. You may save the downloaded video in .FLV, .AVI, or .MP4 formats. Resolution settings are offered; in most cases, it is wise to accept the largest resolution.
YouTube to MP3 converter: in case your 3D screen is broken, or if you are blind, downloading audio only from a 3D movie make sense. It is easy thanks to the YouTube to MP3 converter from the same author as the YouTube Downloader HD here above.
Disclaimer: Some YouTube videos have a download button or link, but the majority do not. The YouTube Terms of Service prohibit downloading video clips that lack an official download button or link. You should also be aware that the YouTube FAQ states that downloading a video without a download button or link violates the video owner’s copyright.
Playback 3D videos after download
To playback the video in stereoscopic 3D, use StereoscopicPlayer from 3dtv.at. To check your 3D download feature, go to our 3D movies trailers page and enjoy more than 190 stereoscopic 3D movie trailers stored on YouTube in true 3D stereoscopic format. We have also a new 3D Games trailers page.
An alternative variant for LINUX users to StereoscopicPlayer is Bino, a free stereoscopic player with less features.
