Bigger than the webpage, smaller than full-screen, and resizable!
I am no longer updating this page!
YouTube has added essentially everything this page does into the Theater Mode Player in their new UI.
You can try out the new UI by going to http://www.youtube.com/new
How to use: 1) Enter a link to a YouTube video.
2) Press Watch! You will be redirected to the full player.
3) Use the browser's back buttons to return to this page.
Enter a video link
Whoops! Link is invalid, please check it and try again.
404! Could not access the video for that URL, please check the link and try again.
Success! Right-click an image, then press "Save as" to save it.
