It’s a good idea to use a bookmarklet to download videos from YouTube.
You could save the following link as a bookmarklet by dragging it to your Links bar (in Firefox, Safari) or right-clicking and adding it to your favorites (in Internet Explorer, Opera):
When you want to download a YouTube video, just click on “Get YouTube video” and the bookmarklet adds a small link below the video’s description: “Download: standard MP4“. Click on that link and you’ll download the video. For some videos, you’ll also see the option to download the HD version like – “Download: standard MP4 | HD 720p | HD 1080p“.

TV manufacturers want to bring that experience to your living room with 3-D displays that work much like the ones in the theaters. Major consumer-electronics companies, including Panasonic, Mitsubishi and Sony, are betting on 3-D, with compatible TV sets planned for the market in 2010.
To understand why, here’s a short primer on how our vision works. Our eyes are about 3 inches apart, which means each eye sees a slightly different perspective of the same scene. The brain takes images from both eyes, fuses them together and uses the difference between the images to calculate distance, creating a sense of depth.
Getting the 3-D effect at home involves tricking the brain into doing something similar with the images that it gets from a TV set. But that’s not a trivial problem: TV makers have to figure out a way to precisely show a set of slightly different images to each of your eyes.
So how do they do that? Here are the key technologies that are making their way into 3-D TVs.
