The experimental interface for Google Video includes a link to "search options" which lets you refine the search results without visiting a special page. The format has been tested for web search, image search and now Google Video. To try the new interface, go to Google Video and paste in the address bar the following JavaScript code:

javascript:document.cookie= "PREF=ID=019225467b404e0a:LD=en:NR=10:CR=2:TM=1237492874:LM=1237830701:L=0p0CnAA:GM=1:WF=3:S=yzmVZ9RVMzDrZxRY;path=/; domain=.google.com";void(0);
