I watch most of my videos through DuckDuckGo now. How it works:
Visit DuckDuckGo.com
Do a search and click videos.
Click the image, not the video title, to view it in DuckDuckGo's shell.
Another is
http://www.viewpure.com/
You can type the YT URL in there to view it, or drag the "purify button" to your favourites bar (make sure you have Javascript enabled though) and click on it when watching a YT vid.
