All you need to so is change it as follows:
And you should be able to see the video in higher resolution. Neat!
If you are using Firefox (which is a good idea in any case), there is already a greasemonkey plugin script that can do that for you automatically. But i am one of those who don't like Greasemonkey, so I've come up with my own Bookmarklet to do this quickly and easily:
Youtube: Switch to High-Resolution
To use this, follow the instructions below:
Internet Explorer Users:
- Right click on the link above and select "Add to Favorites..."
- Internet Explorer should (rightly) should you a security alert saying "You are adding a favorite that may not be safe. Do you want to continue?". That's because this "favorite" (or bookmark as i like to call it) contains some code. Click on the button titled "Yes".
- In the next box (titled "Add favorite") click on the button titled "Ok" and you are set!
- Next time you are trying to watch a video on youtube.com, select "Youtube: Switch to High-Resolution" from under the Favorites menu.
- Right-cilck on the link and select "Bookmark this link"
- In the next box, click on the button titled "Ok"
- Make sure the "Bookmarks Toolbar" is checked under View → Toolbars.
- Drag the link on your bookmarks toolbar
Please feel free to post any problems, questions as comments. Needless to say, feel free to look at the code
